SSTRX-1000 Satellite Transceiver

The SSTRX-1000 S-Band Satellite Transceiver features an extremely compact and robust design. It has been designed to operate very reliably within the severe environments of satellites and other space vehicles and has been qualified for the use within LEO-satellites.

The SSTRX-1000 System operates in the S-Band frequency band. It is optimized for bi-directional transmission of commands and telemetry data between the ground station and the satellite.

The SSTRX-1000 Transceiver System consists a BPSK Telemetry Transmitter, a Telecommand Receiver with integrated a Bit Synchronizer/Data Regenerator and a Diplexing Filter.
