C Ilat Product Brochure Net-Centric System for Tactical Satellite Networks Gilat's GLT network unifies a variety of terminals: fixed, on-the-move, or on-the-pause, in a single platform. Dynamic and flexible, this network addresses any operational need. PAMA- or DAMA-configurable, it offers efficient space segment utilization. At the heart of this network is the GLT/MLT modem with its innovative waveform -ACSM (Adaptive Coding Spreading and Modulation). This modem is used in several terminals: fixed sites with GLT1000 modems, Satcom-on-the-Move terminals with the military MLT1000, or the quick-deploy SOTP manpack terminal -the SatTrooper1500 or 2000. When a large number of remote terminals are used and the traffic patterns are such that bandwidth sharing is allowed, the modem can also operate in a Point to Multi Point (PtMP) configuration. This saves satellite bandwidth, making network operation more efficient. In PtMP, a single outbound (OB) carrier is shared by all active remote terminals in the network. The outbound traffic to the terminals is multiplexed to a single carrier using time division multiplexing. All modems receiving this OB signal filter out the messages intended for them. Filtering is based on terminal ID. In some applications, fixed bandwidth allocation (PAMA) is not the optimal solution. One example is when a large number of terminals are offline or in storage and require going operational very quickly without operator intervention. In other networks, only some of the terminals are active at any given time, or transmitting part of the time according to the mission or the application. For these cases, the system uses a DAMA (Demand Assigned Multiple Access) mechanism. • High-performance carriers with speeds up to 80Mbps • Innovative ASCM waveform with full adaptivity and high efficiency • End-to-end solutions within the same network and NMS • Dynamic allocation of bandwidth according to operational needs GLT Network gilat.com | [email protected]

System Features ACSM Waveform The innovative ACSM (patented) waveform was designed to allow an optimal adaptive communication link from poor channel conditions (Signal to Noise (SNR) of -13 dB) to medium and high SNR conditions. It utilizes direct sequence spreading technique to enable operation at very low SNR. The hub is the heart of the network. Installed in a 19” rack and located in an earth station/teleport together with the RFT and the hub antenna, it transmits and receives signals towards the terminals via the satellite. Various RF bands are supported: C-band, Ku-band, Ka-band and X-band....
