High Performance:
Offers high-speed data transfer with symbol rates up to 5 MBd using BPSK, QPSK, or 8PSK modulation. Satlab SRS-4 The is a high-speed, full-duplex S-band
: Satlab built this radio to be "flight-proven." In our story, when the satellite emerges from the dark side of the Earth and hits the first bit of sunlight, the SRS-4 boots up instantly. It catches the signal from a ground station with a sensitivity of —essentially hearing a whisper from across a continent. The Success FR-01: The system shall track all major satellite
On-Orbit Upgradability:
The system is fully software-upgradable while in orbit, allowing for mission-critical updates and performance improvements.

System Design and Functional Overview
Below is a detailed technical write-up structured as a comprehensive , which serves as the core content for an SRS document regarding the Satlab S4 (a common model often associated with this nomenclature) or generic Satlab GNSS ecosystems.
- 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.
: Space is a harsh environment with a limited "power budget." The SRS-4 is designed to be incredibly efficient, providing up to
