CubeSat S-Band Transmitter

Full-duplex Low-power S-band Transceiver

Basic Price € 14,000

This full-duplex low-power S-band Transceiver is designed by NanoAvionics’ partner Satlab for TM & TC on micro- and nano-satellites.

The transceiver operates on the ITU space operations S-band frequencies with GMSK modulation and CCSDS recommended channel coding, enabling integration with both individual and commercial ground station networks.

The unit has separate filtered RF connections for input and output, allowing for different receiving and transmitting antennas.
