About
The Satlab SRS-3 is a full-duplex, low-power S-band transceiver designed for telemetry and telecommand (TM & TC) on micro- and nanosatellites. The self-contained system operates on ITU space operations S-band frequencies with integrated transmit and receive filters, LNA and power amplifier, requiring only passive external antennas. The SRS-3 is highly configurable — transmit and receive frequencies, bit rates, output power and framing configurations are all adjustable on-orbit. GMSK modulation is used on both uplink and downlink. The SRS-3 has demonstrated reliable flight heritage since 2019, with over 100 units delivered to customers worldwide. With TRL 9, it is fully qualified and operational in its intended environment.
