Srs-4 Satlab — Patched
SatLab SRS-4 is a high-speed, full-duplex S-band transceiver specifically designed for micro- and nano-satellites. It is used for telemetry, tracking, and command (TT&C) as well as high-speed data transfer. Key Features & Specifications Performance : Supports variable transmit symbol rates up to and data rates up to Modulation : Utilizes BPSK, QPSK, and 8PSK modulation schemes. : Includes integrated AES-256-GCM link-layer encryption and authentication. Interfaces : Features CAN-bus and RS-422 interfaces using the CubeSat Space Protocol (CSP) , plus an Ethernet interface for IP traffic. Physical Design
- FR-01: The system shall track all major satellite constellations: GPS, GLONASS, Galileo, BeiDou, QZSS, and SBAS simultaneously.
- FR-02: The receiver must support multi-frequency reception (L1, L2, L5) to mitigate signal multipath errors in urban environments.
- FR-03: The system shall automatically switch between RTK fixed, RTK float, and Autonomous positioning modes based on signal availability.
