C Ilat Product Brochure Compact and Ruggedized SOTM Antenna For many defense and security applications, Satcom On-The-Move (SOTM) is the only choice to establish reliable, continuous, quickly deployable broadband communications. SOTM provides a significant communication advantage for defense and security applications such as military C4I on-the-move, homeland and national security applications and wide-scale backup communications for rescue services and emergency responders. The RaySat SR300-M antennas offer compact size and are lightweight and MIL-STD compliant. They feature a reliable, twoway antenna system that enables real-time broadband satellite communications, primarily for voice and data on-the-move or on-the-pause. The RaySat SR300-M antennas feature an advanced flat panel array, which covers both the Rx and Tx bands. Minimal size, weight and power (SWaP) permits installation on small vehicles and marine vessels. The antenna system's light weight ensures easy and safe mounting for quick and easy operation by non-technical personnel. The antennas feature multiple onboard tracking sensors, enabling accurate tracking, short initial acquisition and instantaneous reacquisition. The SR300-M can be offered as part of a complete, integrated SOTM terminal with a unified management system. The terminal includes seamless mechanical integration of a Gilat/Wavestream BUC and a Gilat MLT1000 modem. The integration with the Gilat special-purpose SOTM modem allows for operation at low SNR conditions. When integrated with 3rd party modems, the antenna is supplied with an Antenna Control Unit (ACU). • Compact SWaP • MIL-STD compliant • Easy and quick installation on small vehicles and vessels • Rapid auto-acquisition, tracking, and re-acquisition • Optional integrated terminal including an antenna, RaySat SR300-M gilat.com | [email protected]
