OrbiCraft Pro SXC-UHF-02 VHF transceiver is made in the form of a board that is connected to the board stack of the main electronics unit of the spacecraft via the PC104 connector. The transceiver board contains an SMA connector for antenna connection and an antenna deployment interface.
The transceiver operates at a tunable frequency from 434-436 MHz in a bandwidth not wider than 20 KHz. This achieves a transmission rate of up to 9600 baud in the GMSK modulation mode, sufficient for the exchange of telemetry, commands and data with the satellite payload. The maximum output power is 1 W, and the sensitivity is 119 dBm, optimized for transmission with LEO, typical for recipients of information from the payload. The VHF transceiver operates in the temperature range -40+ 85 deg С, weighs about 40 grams. The transceiver is compatible with OrbiCraft-Pro PC104 interface, additionally has an asynchronous UART interface. The device transmits heartbeat packets and onboard time signals to the onboard CAN bus. Real time clock (RTC) is connected to an autonomous power source.
