The PULSAR-TMTC is a compact telemetry and command radio designed for nanosatellite missions, compatible with the CubeSat standard with a CubeSat kit PC/104 form factor. The transceivers are ideal for space missions where a low data–rate uplink and downlink is required as well as a robust lower data-rate back-up radio for a higher data-rate radio. The AX.25 protocol implemented is popular among amateur radio enthusiasts. A transparent downlink mode is available with a CCSDS compatible ½ rate convolutional encoder.

PULSAR-TMTC implements 9600 bps GMSK and 1200 bps AFSK and operates in full-duplex (VHF/UHF) or half-duplex (UHF) mode. A combination of AFSK and GMSK is configurable for transmit and receive. These modes are selected as an I2C command and the default mode will be selected if a reset occurs. The default mode can be requested at time of production. The transceiver offers transmit and receive frequencies covering both amateur and commercial bands.
