About
Designed for small spacecraft, the SDR provides scalable processing capability and multi-application support within a single, modular radio subsystem. This compact, high-performance SDR platform enables flexible satellite communication from 70 MHz to 6 GHz. It supports multiple RF frontends and offers in-orbit reconfigurability through an embedded Linux system. The SDR features a software-defined architecture with multiple RF frontend, bringing flight-proven reliability, flexible RF configuration, and in-orbit reconfigurability into a compact radio subsystem designed for evolving satellite missions. From single-spacecraft operations to constellation-scale deployments, it provides the adaptable communication architecture needed to support stable, scalable, and future-ready space applications. It is part of the Radios & Antennas portfolio, which delivers flight-ready communications hardware for LEO missions, offering resilient TT&C links with band and configuration options in compact, integration-friendly form factors.
