CubeSat and SmallSat S-Band Transceivers

The minimum order quantity for this subsystem is 2 pieces.

SRS-3 is a low-power, full-duplex S-band transceiver for TM/TC on micro- and nano-satellites. It operates on ITU space operations frequencies with integrated filters, LNA, and power amplifier, requiring only passive external antennas. It is highly configurable in orbit, with adjustable frequencies, bit rates, output power, and framing.

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

These full-duplex S-band Transceivers are designed by NanoAvionics’ partner Satlab for TM & TC and high-speed data transfer on micro- and nano-satellites.
