6 1 Introduction 1.1 Scope This document is intended for giving system engineers, support engineers, and installation and service personnel the necessary information to plan, install, operate and maintenance a TSAT network. A brief trouble-shooting guide is also included. Technical information about the TSAT system concept, transmission system and communication protocols can be found in the document "TSAT System Description". The Supervisory Terminal and Network Management System is described in the "Supervisory Terminal User Guide". 1.2 TSAT 3000 System Introduction The TSAT 3000 satellite communication network is dedicated to low-to-medium data rate communication via satellite. The Remote Terminals are controlled by one common HUB Station in a full duplex closed star network configuration, see Figure 1-1. The unique design of TSAT 3000 introduces low-cost solutions to traditional problem areas in low data rate satellite communication, such as frequency stability, phase noise, and interference requirements. Flexible interface and protocol options offer cost-effective communication solutions for data collection, remote monitoring and control and transaction applications. 9.6kbps 128kbps Hub Station m Remote Terminals m Figure 1-1 TSAT 3000 Closed Network Low data rate: 9.6kbps 128kbps enables low transponder load. The outbound link, from the HUB to the RT s, is running continuously, addressing and commanding the Remote Terminals. The Remote Terminals share one or several inbound links either by time division multiplexing or by random access. Any conventional Ku-band or C-band communication transponder can be used Closed network: TSAT 3000 is a dedicated, private network.

7 The TSAT 3000 design allows a complete HUB station comparable in size and complexity to traditional VSAT s (Very Small Aperture Terminals). Because of the extremely low-cost HUB station, TSAT 3000 requires low investments in earth station equipment. The efficient utilisation of satellite power and bandwidth gives low operational costs, enabling cost-effective solutions even for small networks. The modular design enables flexibility for future extension of network capacity. Adding more inbound link frequencies, requiring only the addition of an extra Main Unit in the HUB Station will increase the inbound link capacity. If the network grows beyond the capacity of the outbound link, the network can be divided into sub-networks by adding new outbound links. Possible applications include: Collection and distribution of data, i.e. environmental, ecological and security surveillance. Remote monitoring and control (SCADA), e.g. within electrical generation, transmission and distribution, oil and gas pipelines, water management. Transaction oriented networks, i.e. credit-card verification, on-line betting, automatic teller machines (ATM).

8 2 HUB Station and Remote Terminal Site Requirements 2.1 Introduction The following sections describe the requirements for the TSAT network sites, including mechanical requirements for the HUB Station and Remote Terminal sites, pointing direction, and wind load. 2.2 Antenna Site requirements Site elevation and azimuth angles The site elevation and azimuth angles must be known before a site survey can be performed. The antenna site elevation and azimuth angle, and distance to the satellite, can be calculated when the following parameters are determined. The location of the satellite in the geostationary orbit, normally given in degrees with references to the zero meridian (Greenwich, London). Angle is positive towards east. Site longitudinal location (degrees). Site latitudinal location (degrees). The required parameters are: 6 re = m ( earth radius) 7 rs = m ( distance earth center to geostationary orbit) α = lattitude antenna site θ = ( longitude antenna site) - (longitude satellite position in geostationary orbit) The antenna site elevation angle, from horizontal plane, is given by: 2 / [ ] 1 2 ) ( ( r r ) ( ) ε = arctan cosα cos θ / / cosα cosθ e s 1 The antenna site azimuth angle, from true north, positive angle clockwise, is found from the equation: a = arctg tg θ / sin α ( ( ) ( )) The distance to the satellite is given by: 2 2 1/ 2 d = r + r 2 r r cosα cosθ [ s e s e ] There exists programs that would do these calculations automatically, with satellite position and site coordinates as input Signal path obstruction The antenna site must have an unobstructed bore sight to the satellite position in the geostationary orbit, as shown in Figure 2-1. An obstruction inside this envelope will result in reduced signal to noise ratio, and increased transmit signal interference levels which are not compliant with ETSI and satellite operator requirements.

In addition, the specification given in ETSI EN state that under the condition of 100 km/h maximum wind speed, with gusts of 130 km/h lasting 3 seconds, the antenna or other parts of the structure shall not show any sign of permanent distortion and shall not need repointing after the application of the wind load. A load of 20 mm of ice coating on the antenna surface should also be considered in areas where this condition might occur. The supporting structure should therefore be constructed with this in mind, or existing structure should be examined carefully, before the antenna mount is assembled. Table 2.1 lists the wind load at 50 m/s, and the ice load for a 20 mm ice coating. Antenna size [cm] Wind speed [m/s] Ice load [kp] (20 mm ice coating) Wind load [kp] (1 kp 9.8 N) m/s m/s m/s m/s ~200 ~1000 Table 2.1 Wind load and ice load The correspondence between various wind speeds, wind loads and antenna diameters can be found from values given in Table 2.1 and the following equation: 2 2 P = P ( v / v ) ( ø / ø ) (for circular antennas) where the index 0 and 1 indicates data set 0 and 1: P x = wind load for data set x ν x = wind speed for data set x Installation, Operation and Maintenance Guide, October 2008 Page 9 of 36

10 φ x = antenna diameter for data set x 2.4 Antenna mount methods Pole mount The HUB Station antenna diameter is normally 1.2m or 1.8m. The 1.2m normally fits a pole dimension of 3 inches (76 ± 1 mm), while the 1.8m antenne normally fits a pole dimension of 4.5 inches (114,3mm). Other HUB antenna dimensions can also be used. For assembly and mounting of the HUB antenna see the description supplied with the antenna. The Remote Terminal antenna diameter is normally 96 cm or 1.2m, and uses 3 inch pole size. For assembly and mounting of the Remote Terminal antenna see the description supplied with the antenna Wall mount / Ground mount If a wall mount is used, the distance from the wall to the pole must allow the antenna to be rotated sufficiently to point to the satellite position in the geostationary orbit se. With the 120 cm antenna the distance from the wall to the pole must be 630 mm to allow pointing parallel with the wall. See the documentation supplies with the mounts for assembling and mounting. 2.5 Cable requirements Data cable requirements See the interface specifications in chapter 7 for details. Serial application data interfaces (Serial 1 & 2): The two asynchronous interfaces on the Main Unit comply with the RS-232 standard, DCE pin-out. The cable environmental specifications must satisfy the local conditions. The maximum cable length according to this standard is 15 meters at 9600 bps. Practical use has shown that this length normally may be exceeded without observable degradation up to 30 meters. However, in noisy environments even distances of a few meters may give unreliable performance. In this case, or for long cable lengths, the signals must be transmitted via short haul modems or data signal converters. For the use of short haul modems, please refer to the short haul modem documentation. LAN interfaces (LAN A & B): The LAN interfaces comply with Ethernet RJ45 standard, and is auto negotiating, 10/100MHz, full/half duplex and auto MDI/MDIX. In addition, there is 1 x Expansion interface (for future use), and 1 x Console and 1 x Modem interfaces (RS-232, RJ45) for m&c purposes RF Front End cable requirements TSAT 3000 The RF Front End is connected with the Main Unit with two 50ohm coaxial cables (cable harness kit CKA 3500). The cable specifications depend on the distance between the Main Unit and RF Front End. The cable loss must be <20dB on the Tx L-band signal ( MHz) and <20dB on the Rx L-band signal ( MHz). The maximum cable voltage loss is 0.5 V for DC power supply. The 10 MHz reference oscillator signal is multiplexed onto the coax cable. Normally, coaxial cables have negligible losses at 10 MHz. N-type 50ohm connectors are used on both the RF Front End and Main Unit. For long distances, low-loss coaxial cables are required. The cables must satisfy the local outdoor environmental specifications. Installation, Operation and Maintenance Guide, October 2008 Page 10 of 36

11 3 HUB Station Installation 3.1 Introduction This section describes the installation procedure for assembling and mounting all TSAT 3000 HUB Station modules, including the procedure for pointing the antenna towards the satellite. The TSAT 3000 HUB Station normally consists of the following modules, shown in fig 3-1: 1. Antenna 2. BUC Transmitter TX LNB Receiver RX HUB Main Unit Assembly MUA Transmit/Receive coax cable assembly CKA Supervisory Terminal Assembly Figure 3-1 TSAT 3000 HUB Station Modules Other required units are: Antenna mounting structure including pole Data cables between application equipment and TSAT if not supplied together with the HUB Station. Power supply for Main Unit 3.2 Antenna unit assembly Assemble and mount the antenna according to the description supplied with the antenna. The antenna-mounting pole must satisfy the antenna site requirements discussed in section Antenna pointing Introduction Installation, Operation and Maintenance Guide, October 2008 Page 11 of 36

12 To point the antenna, the elevation and azimuth angles at the site must be known, see section 2. The procedure described below assumes that a Ku-band TV carrier is available at the same geostationary orbit position as the satellite of interest. If this is not the case, personnel familiar with pointing antennas to satellites must operate a beacon finder or spectrum analyser. Three parts, BUC (Tx unit), LNB (Rx unit) and waveguide with LPF (Low Pass Filter) make up the TSAT3000 RF Front End. The RF Front End are available in several versions, see table 3.1, all combinations are legal. On TSAT3000 HUB Main Unit the Rx L-Band connector can be used in connection with any TSAT3000 RF Front End to monitor the received TV carrier. This connector is an option. Frequency range (GHz) Local oscillator (GHz) Input/Output frequency range (MHz) Tx: Input: Rx: Output: Rx: Output: Rx: Output: Table 3.1 RF Front End frequencies for TSAT 3000 The pointing procedure is based on using a "satellite finder", an instrument for monitoring received TV carrier levels in the Ku-band. Normally the TV sound can be monitored, and some models display the TV picture. The signal level is displayed, allowing the antenna to be adjusted to the maximum receive gain position. These instruments normally assume the use of standard LNBs with a local oscillator of 10 GHz. The input frequency range is therefore normally 950 MHz to 1700 MHz. The TSAT RF Front End uses an PLL LNB, these LNBs needs a 10MHz external reference signal. Most instruments used for pointing antennas don t supply this. It is therefore normally necessary to mount a standard TV reception LNB for the antenna pointing, and mount the TSAT3000 RF Front End after the antenna is adjusted to the correct position. Installation, Operation and Maintenance Guide, October 2008 Page 12 of 36

13 3.3.2 Required tools and instruments The procedure below is based on finding a TV carrier at the same geostationary orbit position, and adjusting the antenna bore sight to give a maximum signal level. The antenna will then be at the correct position also for the TSAT 3000 carriers. It is also necessary to adjust the rotational angle of the RF Front End to adjust the cross polar interference level to the specified level. The ETSI specifications state that the polarisation angle should be aligned with an accuracy better than ± 1 degree, corresponding to a cross polar level lower than - 35 dbc (see also section ). The recommended equipment for pointing the antenna is: Satellite finder, e.g. Kathrine MSK 1 Compass with accuracy better than 1 degree. Recommendation Silva type: SM360 LA. Knowledge of true north to magnetic north angle Map over the antenna site area Knowledge of TV carriers in the same and adjacent satellite positions Inclinometer with a bar/rod slightly longer than the antenna diameter, resolution better than 1 degrees degree and accuracy +/ degree. Recommendation: Silva type: CM360 % LA. Low cost standard LNB that can be mounted to the antenna horn wave guide Recommended tools for adjusting the RF Front End rotation (cross-polar adjustment): Inclinometer with bar/rod suitable for measuring the RF Front End rotation angle Antenna pointing procedure Pre-adjustment of antenna Determining the elevation and azimuth of the antenna is described in section 2. The antenna elevation can be adjusted to the approximate position by using the inclinometer and a bar across the main antenna reflector, as indicated in figure 3-2. The correspondence between the main antenna reflector and bore sight angle of the antenna differs slightly from antenna to antenna, and can be found in the antenna assembly description. The antenna azimuth angle can be adjusted to the approximate position by using a compass. The magnetic field conditions of the site may influence the compass strongly. If the site is located near large buildings, the compass direction may be completely wrong, with large fluctuations over only a few meters distance. To check this, move the compass a few meters to each side. A map over the site may be used to establish a reference direction. The azimuth angle of interest can than be adjusted by using the compass to rotate the antenna relative to the reference direction. The antenna should now be pointing approximately in the right direction (within a few degrees). Installation, Operation and Maintenance Guide, October 2008 Page 13 of 36

14 Figure 3-2 Antenna elevation pre-adjustment α = angle between main reflector and antenna bore sight γ = inclinometer angle β = site elevation angle Satellite acquisition Mount the TV reception LNB to the antenna horn. Connect the LNB to the satellite finder instrument, and adjust the satellite finder to monitor an available TV carrier at the satellite position. (Please refer to the manual for the LNB and satellite finder instrument for detailed operating instructions). Rotate the antenna back and forth a few degrees in the azimuth plane, and observe if the TV carrier of interest is received. If no carrier is received, adjust the satellite finder to receive other TV carrier. If the result is still negative, repeat carefully the procedure for pre-adjusting the antenna, or adjust the antenna to point to an adjacent satellite with a known TV carrier, i.e. ASTRA. When a known satellite is found, this position can be used as reference. When the correct carrier on the correct satellite is found, peak the signal level by adjusting the antenna carefully in both the elevation and azimuth plane several times, since the adjusting one of the planes also slightly effect the direction in the other plane. Fix the antenna bracket in the position giving the maximum signal level. Ensure that the maximum signal level is received also after the antenna bracket has been fixed. Remove the LNB from the antenna horn. The antenna should now be pointing with a maximum gain towards the satellite of interest. 3.4 RF Front End Mounting RF Front End assembly The BUC and LNB are mounted to the OMT using supplied screws, the LNB must be mounted on the filtered end. Transmit and receive are mounted in a 90 degrees angle to each other. One example of mounting is shown in Figure 3-3 RF Front End assembly, OMT and filter are normally supplied with the antenna and are only shown here as example. Installation, Operation and Maintenance Guide, October 2008 Page 14 of 36

15 Make sure that there are O-rings between all parts. See the antenna assembly instruction for OMT and feed horn assembly. LNB Filter BUC OMT Figure 3-3 RF Front End assembly RF Front End rotation adjustment The satellite transponder operates with linear polarisation, either horizontal (H) or vertical (V). The polarisation must therefore be known when installing the RF Front End. The orientation of the BUC in vertical polarisation for Tx is shown in figure 3-4. Figure 3-4 Orientation of BUC in vertical polarisation for Tx RF Front End rotation adjustment for minimising cross-polar radiation level. Installation, Operation and Maintenance Guide, October 2008 Page 15 of 36

16 The RF Front End must be set at the correct rotation angle with an accuracy within 1 degree, corresponding to a cross polar level below -35 dbc. The antenna is normally delivered with a fixed mount. In this case, the angle is a function of the antenna site position and the satellite position. figure 3-5 displays graphs for the cross-polar rotation angle with reference to the gravitation vector, as a function of the azimuth angle, with the elevation as the parameter. The same data is tabulated in table 3-2. Normally, the horizontal polarisation direction is parallel to the geostationary orbit, and vertical polarisation is then perpendicular to the geostationary orbit. This orientation is assumed in fig 3-5 and table 3-2. Some satellites have a polarisation offset that also must be taken into account. Before a new satellite is taken into use, the satellite operator should confirm this information.

22 4.7 Protective earthing The Main Unit must be properly connected to earth to the M4mm screw with earthing mark on the connector wall. 5 HUB Station Operation 5.1 Pre-operational requirements Before starting up the HUB Station, the procedure described in section 3 must be completed, including interconnecting all the modules as described. It is important that the satellite control centre is contacted for line-up test, in some cases separate test frequencies can be supplied. 5.2 Main Unit configuration The HUB Main Unit must be configured with the correct parameters, including operating frequencies and output power, using the configuration programs or the NMS SW. This initial configuration of the HUB Main Unit must be done with the Tx coaxial cable disconnected. 5.3 Supervisory Terminal configuration Start the Supervisory Terminal program, and confirm that the Supervisory Terminal is connected to the Main Unit via the LAN interface. 5.4 HUB Station power-up The Reference Oscillator inside the HUB requires a few minutes to stabilised after a cold start. The 10MHz reference signal is therefore muted at start up, and the HUB will not transmit until the reference is stable. This may take up to 5 min.

Red flash when packet errors are detected. Additional and more detailed information on start-up sequence status and progress can be monitored as messages on the Supervisory Terminal. 5.5 Circuit-switched protocol operation The HUB Station circuit-switched application port(s) are either the 2 asynchronous serial ports on the HUB Main Unit, and/or asynchronous PC COM-ports on the Supervisory Terminal, and/or asynchronous PC COM-ports on a COM Port server connected to the Supervisory Terminal via a LAN connection. The Supervisory Terminal application port configuration must match the application port configuration of the connected application (ref. Supervisory Terminal User Guide for configuring the PC ports). When the Supervisory Terminal port(s) are correctly configured, and the application is started, application data can be monitored in the Supervisory Terminal, confirming normal operation. 5.6 LAN (TCP/IP) operation To connect to the local LAN for TCP/IP application data over TSAT, connect one of the LAN interfaces on the Main Unit (LAN A or LAN B) to the local area network. In addition, static routes for the traffic over TSAT need to be configured. Installation, Operation and Maintenance Guide, October 2008 Page 23 of 36

24 5.7 Supervisory Terminal Operation Introduction This section gives general guidelines of how the Supervisory Terminal functionality may be used to manage the TSAT network. The detailed procedure of the Supervisory Terminal functions is given in the "Supervisory Terminal User Guide" Network Status monitoring The status and network management windows of the Supervisory Terminal monitor the status of the network. The status messages may be logged to a file. The daily routines for the log file management strongly depend on the user requirements and the property of the application, i.e. if the application itself gives a warning if an error occurs in the TSAT network. It is therefore difficult to give general guidelines in this matter. A suggested procedure may be to open a log file once a week and store the log files for some months Logging of statistical data Selecting the automatic polling of "All active links", and opening a log file, will result in the logging of the E b /N 0 ratio on all active links with the specified time interval. By monitoring the E b /N 0, one may observe changes in E b /N 0 ratio that may suggest the need for a site inspection, or indicate a potential problem with a RT at an early stage. Again it is the user requirements that determines how and if this function should be used. A suggested guideline is to set the polling interval to once per day, and inspect the log file once per week. 5.8 Adding new Remote Terminals If the network is expanded with Remote Terminals, the new Remote Terminals must be defined in the Supervisory Terminal. The HUB CCU must also be configured with a sufficiently large parameter for the number of Remote Terminals in the network. When the Remote Terminal is installed, it will automatically log on to the network after power-up. If the RT is not defined in the Supervisory Terminal or HUB CCU, an error message will be displayed when the RT tries to log on to the network. 5.9 Removing Remote Terminals from the network If a Remote Terminal is turned off, the HUB CCU will recognise that the Remote Terminal has stopped to respond, and sends a "Link is Down" message to the Supervisory Terminal. The time required to recognise a Remote Terminal shutdown depends on the network traffic and network size Protective earthing The Main Unit must be properly connected to earth to the M4mm screw with earthing mark on the connector wall. Installation, Operation and Maintenance Guide, October 2008 Page 24 of 36

25 6 Remote terminal operation 6.1 Introduction Before being set into operation, the procedure given in section 4 must be completed, the power supply must be installed, and the Remote Terminal must be correctly configured in agreement with the application equipment configuration. Connection and disconnection of the connectors (POWER and RF Front End ports) must only take place with the power supply turned off. In some cases the satellite control centre must be contacted to do line-up tests before powering the Remote Terminal. 6.2 Remote Terminal Configuration The Remote Terminal is configured by connecting one of the LAN ports to a PC running either the Supervisory Terminal Program, or another configuration program. Make sure the unit is correctly configured before the TX-cable is connected. 6.3 Remote Terminal power-up The start-up sequence progress can be supervised by monitoring the LEDs on the Main Unit front: Seq. Stage description stage no 1. After power up: Power system verification. Checking all power levels LED indicator LED status during operation LED status upon completion Power Red flash OK: Steady green Not OK: Flash yellow or steady red. 2.

26 6.4 Application port operation Async. ports Connect the Remote Terminal serial port(s) to the application equipment (serial 1 or serial 2). Confirm that the application equipment operates normally, communicating with the HUB application equipment. If so, the async application ports are in normal operation LAN ports Connect the Remote Terminal LAN port(s) to the application equipment (LAN A or LAN B). Confirm that the application equipment operates normally, communicating with the HUB application equipment. If so, the LAN application ports are in normal operation. If problems arise in operating the application ports, please refer to the section "Trouble-shooting". As described in section 9, the Remote Terminal operation can also be confirmed from a PC with TSAT diagnostics software, independent of any application equipment.

29 8 HUB Station and Remote Terminal Maintenance 8.1 Introduction The maintenance and service instructions for the HUB Station and Remote Terminal are given in this section. The procedure of upgrading or replacing Main Unit software or hardware is also described. Be sure that the unit is powered off before any maintenance is performed. Normally, a minimum of maintenance is required. When problems arise, the normal approach will be to try to identify which unit is faulty, and return this unit for repair. The units which can be replaced are the Main Unit, the Transmitter (BUC) and the Receiver (LNB). 8.2 Normal maintenance The HUB Station does not require much maintenance under normal conditions, except log file management of the Supervisory Terminal. The HUB high stability reference oscillator frequency should be verified once every year, and adjusted if necessary. This can be done by using the Network Management Software. It is also recommended that the site is inspected once a year and that the points listed below are checked. Antenna Visual inspection of: Protective feed horn cap Antenna mounting bracket Support structure stability Grounding cable RF Front End Visual inspection of: Feed horn mount Cables and connectors to Main Unit Main Unit Visual inspection of: Main Unit mounting screws Main Unit cables and connectors Power supply Visual inspection of: Power supply connection to mains or battery system Power supply connection to Main Unit cable 8.3 Main Unit Softare / firmware upgrades. All software and firmware modules (Main processor, DSP processor and FPGAs) can be upgraded, both through a PC locally connected to the unit, and also across the TSAT network via the satellite link (normally from the HUB to any or all of the RTs). Installation, Operation and Maintenance Guide, October 2008 Page 29 of 36

30 8.4 Supervisory Terminal service/maintenance The Supervisory Terminal PC normally requires no maintenance, other than management of log files as described under "Supervisory Terminal Operation". If a failure occurs, contact PC service personnel, or the local service organisation. 9 Trouble-shooting 9.1 Supervisory Terminal Normal operation When the network is operating normally, the "TSAT Network Configuration" window shall indicate the actual status of all defined links: Green icon and "Link is UP" if the RT is on-line Red icon and "Link is DOWN" if the RT is off-line Unexpected situations may arise. In the following, a short description of trouble-shooting procedures is given. The link is UP, but should have been down. The link protocol shall be capable of handling collisions and retransmissions. It may therefore take up to a few minutes before a link falls down until the HUB CCU in the Main Unit changes the status of the link, and sends a message to the Supervisory Terminal. If it seems to take too long, polling the HUB CCU for the link status can check the communication link to the HUB CCU. If a message is received, the communication is OK. If not, check the communication link to the HUB CCU. Check-list for communication link to CCU Cable and connectors HUB Main Unit powered Communication settings OK. The link is down, but should have been UP After reset, it might take up to 5 minutes before the links are opened, due to frequency acquisition and modem synchronisation. Make sure a message is returned when polling the HUB Main Unit for link status. If not, refer to the check list above for communication with the HUB CCU. The HUB CCU in the Main Unit controls the link status. It can be opened and closed by the operator at the Supervisory Terminal with the commands "Open Link" and "Close Link". If the operator at the Supervisory Terminal closes the link, the operator must also open it again before the link status can change, or the HUB Main Unit must be reset. Link status is UP, but is the link really up? To confirm that a link is really up, select the "Poll RT Statistics" command, and select the RT of interest. If the link is up, a message will be received in the status message window, confirming the reception of a statistics packet from the RT. If the link has recently failed, the HUB CCU will in a short time time-out the RT poll request due to the lack of answer, and report a change of the link status to down. This test does however not check the status of the application ports. Are the application ports operating as normal? To check the operation of the application ports at the RT, it is necessary to start a connected application on the RT side, or poll a connected application from the HUB side. The flow of application data can be observed (in hex format) at the Supervisory Terminal by opening the application data window.
