UHF transceiver allows to organize communication of the ground segment with the spacecraft for its control and telemetry. Suitable for use in low orbit as a primary or backup transceiver.

Transceiver operates on 435-438 MHz frequency range. Communication is carried out in half duplex mode through one antenna, while telemetry, telecommands and beacon messages are transmitted via single radio channel. Beacon message composition can be customized during software update, which is conducted via radio as well as via CAN interface.

Features:
- half duplex communication through one antenna
- single radio channel for telemetry, telecommands and beacon signals
- update via radio and CAN firmware interface
- hardware and software watchdog timers
- customizable beacon message composition
- bridge mode from the ground to the onboard bus
- real time clock (RTC) with backup power - AX.25 or USP protocol (with protective coding)
