VTRX VDE-SAT Transceiver
The Satlab VTRX is a half-duplex VDES/VDE-SAT transceiver compliant with ITU-R M.2092-1.
The transceiver is designed for integration on nano- and microsatellites in 500-700 km orbits. The VTRX integrates a multi-channel modem as well as VDE-SAT protocol stack.
An external GNSS-receiver with NMEA 0183 and PPS output is required for timing and frequency control.
