SRS-4 Full-duplex High-speed S-band Transceiver
The Satlab SRS-4 is a full-duplex S-band transceiver designed for high-speed data transfer on micro- and nano-satellites.
The transceiver operates on the ITU space operations S-band frequencies with BPSK, QPSK and 8PSK modulation and CCSDS recommended channel coding, enabling integration with both independent and commercial ground station networks.
