C Ilat Product Brochure Software Defined Radio (SDR) Modem The satellite communications market demands a transformative Software Defined Radio (SDR) solution which overcomes critical industry challenges such as supporting diverse waveforms from multiple vendors to operate seamlessly across different networks, use cases and capabilities. Advanced SDR technology offers unparalleled advantages by enabling the selection of the most relevant waveform for each mission. This flexibility empowers satellite communications providers to achieve seamless multi-vendor integration, unlocking new levels of adaptability and cost-efficiency. Next generation SDR modem technology establishes a strong foundation for future SDR applications, consistently outperforming virtual modem alternatives in power consumption and economic efficiency. The industry's core need is a multi-vendor solution that transcends traditional technological boundaries. By expanding waveform portfolios and fostering strategic collaborations with key technology partners, satellite communications providers can deliver adaptive, high-performance platforms which meet the evolving needs of global defense, commercial, and connectivity markets. SkyEdge IV Capabilities One of the key waveforms supported by the GLT 1500 is the SkyEdge IV waveform - a state-of-the-art, full-scale, SATCOM network designed to meet the demands of any modern defense organization. This field-proven system is optimized for operations across land, sea, and air delivering reliable real-time data feeds to any platform, even in the most challenging field conditions. GLT 1500 SkyEdge IV mode is a high-performance modem designed to equip security forces with ruggedized terminals that can be deployed on vehicles or carried in a backpack. It ensures seamless connectivity for both on-the-move and on-the-pause missions, delivering reliable beyond line-of-sight (BLoS) communication between command and tactical levels for uninterrupted information flow. SkyEdge IV waveform was specifically designed for seamless operation over next-generation Very High Throughput Satellites (VHTS) in GEO and MEO (supporting O3B mPower) constellations. ASCM Waveform GLT 1500 ASCM waveform provides cost-effective, secure, seamless connectivity across land, sea, and air on C, X, Ku and Ka bands using SCPC operation. It enables users to simultaneously run a full range of applications, protocols and tasks with ease. Featuring spread spectrum support, with a spreading factor of up to 8, the waveform facilitates the use of very small antennas while maintaining high bit rates, ensuring effortless operation anytime, anywhere. Minimal setup by non-technical personnel facilitates launch of point-to-point satellite communications. The GLT 1500 SDR offers flexible support for data rates from 32kbps to 80Mbps with modulation, FEC and selectable frame size. This minimizes overhead at high-speeds and reduces delay at low speeds resulting in significant bandwidth savings.
