Fit for Data Gathering The Satcom receivers are typically installed in intelligence gathering centers. A defined procedure will allow for data exchanged over satellite to be read out. After the receivers get Cyclic Redundancy Check (CRC8) Handling Data Frame Length Handling Data Frame Length Handling the command to lock on a satellite carrier, intelligence gathering operators can determine the center frequency of the carrier by using a satellite signal analyzer. The results will allow operators to check what modulation standard and symbol rate are used in the satellite carrier. Finally the Base Band frames can be analyzed and useful intelligence data gathered out of both transport streams (TS) and generic streams (GS). s product portfolio contains a variety of modulation and demodulation equipment for standard and proprietary communication over satellite for data, video and voice supporting protocols such as DVB-S2X (new DVB standard as from March 2014), DVB-S2, DVB-S, DVB-DSNG, DVB-S2 Extensions, MF-TDMA 4CPM, Mx-DMA, Reed Solomon, Viterbi, TPC and LDPC. During the entire operation, the receivers will not touch the integrity of the original content and allow detailed processing of the acquired intelligence. The DVB receivers cover the full spectrum of MODCODs up to 256APSK (including 32APSK short frames) as well as CCM/ VCM/ACM modes and data rates from 1.2 kbps to 425 Mbps. In the MDM9000 modem some specific features for intelligence gathering were included in order to detect and capture hidden data in regular satcom transmissions such as: The MODCODs are combined with a set of encapsulation/ decapsulation methods such as MPE, XPE, GSE, ULE, Base Band Frame and Data Piping.

Based on DVB Standards for Interoperability has always been a pioneer in satellite technology and was at the base of many DVB satellite communication standards available in the market today. Kick-started by, key players in the satellite industry recently called for a new satellite transmission standard to extend the existing DVB-S2 standard. The new standard (called DVB-S2X) was launched in March 2014 and approved by both DVB and ETSI. The full implementation of both the DVB-S2X and DVB-S2 standards are already available on 6000-series modems and receivers. Open standards such as DVB-S2 and DVB-S2X allow for interoperability and avoid vendor lock-in. Today, DVB-S2X already provides gains of up to 51% when compared with DVB-S2. The support of Wideband technology adds another 20% to the equation. These gains exceed the results by proprietary systems in the market. 10 Improvements in DVB-S2X Increased Granularity 64/128/256 APSK Smaller roll-offs Advanced filtering of satellite carriers Increased granularity in MODCODs Shannon Limit Higher order modulation: 64/128/256APSK support Spectral Efficiency (bps/hz) +27% +51% DVB-S2X Linear and non-linear MODCODs Better Implementation of MODCODs DVB-S2 Wideband support Very low SNR support for mobile applications C/N DVB-S Channel bonding Additional standard scrambling sequences to mitigate Co-Channel-Interference (CCI) Figure 2: New DVB-S2X standard improvements 4
Maintaining Integrity of Original Content Getting all the information available out of the satellite carriers is very important for intelligence gathering agencies. All 8192 possible PIDs are transparently passed through for further processing. Small details can provide precious information vital to their objectives. The original Transport Streams and Generic Streams are not modified, maintaining the integrity of the original content. In the process of acquisition and demodulation of a satellite signal the raw data remains untouched as PID-filtering and data handling activities can be switched off in the receivers (no filtering of MAC-addresses). receivers also operate in a mode where the complete carrier is demodulated and have raw Base Band data as output that can be further processed by intelligent engines.

VSAT Broadband Solutions has a large base of installed VSAT systems worldwide. VSAT broadband systems are already reaching hundreds of thousands of consumer households today in Europe, Africa, North and South America, Middle East as well as Asia. Other VSAT installations are used in enterprise, SCADA as well in SME, SOHO and government and defense networks. has two broadband platforms in its VSAT product portfolio. The first broadband platform is the Sat3Play VSAT solution which primarily targets consumer, SME and SOHO Internet access networks over satellite. The second broadband platform is the recently launched Dialog multiservice VSAT solution. The Dialog platform mainly targets enterprise, broadcast, backhaul and government and defense applications. 72 MHz 36 MHz NEWTEC HUB MDM2200 22/3,5 Mbps MDM2200 22/3,5 Mbps MDM3300 45/5 Mbps INTERNET BACKBONE CONSUMER SMALL AND MEDIUM ENTERPRISE LARGE ENTERPRISE Figure 4: VSAT intelligence gathering 6
Interception of VSAT Broadband VSAT modem range VSAT hub range The VSAT platforms typically consist of a hub infrastructure, remote modems or terminals and a Network Management System (NMS) that manages the entire satellite network. For the forward satellite link from the hub towards the remote, the DVB-S2 modulation standard with efficiency enhancing extensions are used (smaller roll-offs, etc.). These can be intercepted by the DVB receivers. The satellite return channel from the remotes to the hub depend on the platform in use. Both the Dialog and Sat3Play platforms have MF-TDMA 4CPM technology on board (closely linked to DVB-RCS2). The Dialog platform extends the satellite return channel with SCPC (DVB-S2 with Extensions, HRC) and Mx-DMA TM (Cross-Dimensional Multiple Access) alternatives. As such, the satellite service provider has the choice between three different return channels depending on the application, throughput requirements and service offering. For the interception of the return channels a combination of hub, modem and NMS infrastructure is required. As such, the scheduling, return carrier pools and return capacity groups typical to MF-TDMA can be simulated to receive the requested data that can be forwarded for further processing.
