R40 Mk III AIS Base Station

Transcription

1 R40 Mk III AIS Base Station The new R40 Mk III AIS Base Station from Saab TransponderTech is a result of our on-going efforts to enhance all our products. The R40 Mk III is equipped with a new Base Station Controller (BSC) which hosts the valuable new features and it is designed to allow for future expansion. With the R40 Mk III, Saab TransponderTech continues to hold its leadership in AIS technology. The R40 Mk III is of course compliant with the R&TTE Directive and is like its predecessors type approved by BSH with reference to AIS Base Station Standard IEC The R40 Mk III AIS Base Station is the main component of a Physical AIS Shore Station as defined by IALA. Its main purpose is to receive data from and transmit data to AIS equipped vessels, travelling within the coverage area of the Base Station. This enables monitoring of ships movements and status in real time. The R40 Mk III can either be installed as standalone or be integrated into a network, such as the market leading AIS Network and the CoastWatch AIS monitoring and control suite by Saab. Type approved by BSH according to IEC test specification for AIS Base Stations Compliant with R&TTE Directive Third generation of AIS Base Station from Saab using the latest technology Excellent performance and reliability through joint development with airborne products Supports fully redundant configurations by advanced embedded Hot Standby functionality Full remote configuration and monitoring Advanced Windows based configuration and monitoring tool software included The R40 Mk III Base Station main characteristics Outstanding receiver sensitivity: Better than -111 dbm Embedded Base Station Controller, enhancing functionality and flexibility MTBF > hours Reception and transmission of all applicable AIS messages Internal memory for storage of data, variable size up to hundreds of GB Built-in Web Server AD-converter SNMP support Selected by the majority of Maritime administrations and Port Operators throughout the world

2 SECURITY SOLUTIONS Autonomous channel management capability for different geographical areas Hot Standby functionality Repeater functionality including repeat filtering Receive only mode Built in support for automatic transmission of AtoN reports (message 21) incl. information on offshore obstacles, e.g. oil platforms, wind farms etc. Optional functionality Separate receive and transmit antenna interfaces Built in Reference GPS receiver, makes it possible to internally generate differential GPS corrections that can be transmitted on the AIS channels Third AIS receiver available for local use and special applications 1 PPS input for external timing Special periodic repeat functionality of received AtoN reports Advanced evaluation of the AIS Data Link status such as SNR, RSSI, link load etc. Channel management via DSC DESIGN The R40 Mk III main parts are the VHF transceiver, GPS receiver, Radio Controller and a Base Station Controller. The transceiver unit contains three independent VHF receivers and one common transmitter which alternates its transmissions between the used channels. The internal GPS receiver s main task is to provide accurate time synchronization. Several external interfaces are available, see specification.

3 SECURITY SOLUTIONS Built in WEB-server for monitoring and control The R40 Mk III has a built-in web server that allows the user to connect to the R40 Mk III via a standard WEB-browser. It allows for quick and easy access to basic monitoring functions such as alarms, GPS functionality, VDL link status, etc. The PSS Configuration and Monitoring Tool which is supplied with the R40 Mk III should be used for more advanced configuration and monitoring. Status monitoring via SNMP The R40 Mk III is an SNMP enabled device which allows it to be remotely monitored by an SNMP Manager. The SNMP agent is embedded in the R40 Mk III. Properties that can be monitored in the base station are alarms status, input voltage, channel load, used satellites, number of satellites found, hot-standby status, connection state, etc. External Timing IRIG-B 003 The R40 Mk III can use an external UTC source, in order to facilitate installations where the internal GPS cannot be used for synchronization or where a synchronization backup is required. The external UTC source can either provide a 1 PSS signal and NMEA time messages or it can be an IRIG-B 003 digital time signal. The IRIG-B 003 format is internationally recognized to provide accurate and consistent timing information. AD-converter The built in AD converter allows for connection of external equipment, e.g. sensor for temperature, humidity, wind speed or battery monitoring. The values read are available on the Ethernet port. Internal Memory for temporary storage The R40 Mk III includes built in non-volatile memory for temporary storage of VDL and status data. This function is used if the base station temporarily loses its connection to the AIS network. When the network connection is restored, the temporarily stored data are automatically transferred from the internal base station memory to the AIS network for storage in a database. The data transfer is a mix of real time information and stored data. Real time data has the highest priority and stored data are transferred when there is available capacity on the network connection. The standard size of internal storage memory is 4 GB FLASH but can be expanded to several hundred GB. A memory of 4 GB gives a storage capacity of approximately 45 days assuming an average VDL load of 40%.

4 SECURITY SOLUTIONS Typical site installation Configuration & Monitoring Tool The R40 Mk III is designed for the highest availability and reliability, resulting in high performance and long trouble-free operation. Additionally it is possible to connect two R40 Mk III in a Hot Standby configuration without adding any extra hardware. Several important parameters are continuousily evaluated in order to monitor the status of the units. This includes for example VSWR and VHF transmission data. The standby unit immediately takes over if a fault is discovered. The picture below shows a typical installation on a Base Station Site, two R40 Mk III in Hot Standby, uninteruptable power supply (UPS), Ethernet switch and cavity filters. The R40 is delivered with an advanced Windows based Configuration & Monitoring tool, PSS Tool. It is used for monitoring and configuration of the R40 Mk III AIS Base Station. Examples of operations performed by PSS Tool are configuration, upload of new software and monitoring of base station status. The PSS-tool can be used locally connected directly to the R40 or remotely via a TCP/IP network. General Configuration The picture below displays the main configuration page in PSS Tool which is used to set the basic configuration of the R40 Mk III. VDL Link Map Viewer PSS Tool provides a graphical view of the AIS VDL Link displaying sent/received messages and reservations. The user can select specific slots to view detailed information on what unit is using the slot and the type of message.
