Summary

The AAC Clyde Space PULSAR-UTRX UHF/UHF Transceiver is a telemetry and command radio for nanosatellite missions compliant with CubeSat standard.

The system has a CubeSat kit PC/104 form factor and operates both uplink and downlink in the UHF range serving both commercial and amateur frequencies. The compact system features a beacon and a DTMF backdoor to increase their reliability in flight.

For transmit and receive, the system offers a configurable combination of AFSK and GMSK modes that are selected as an I2C command. If a reset occurs, the default mode will be selected which can be requested at time of production.

Applications

CubeSat, nanosatellite missions.
