The next generation AAC SpaceQuest TRX-U is a compact single board transceiver for satellite communications in the UHF Band. Designed for CubeSat and SmallSat missions our high-performance TRX-U satellite UHF transceiver is ideal for space missions where a low data–rate uplink and downlink are required and can be used as a robust lower data-rate back-up radio for a higher data-rate radio.
The firmware of this legacy component is changeable on orbit enabling upgrades over the lifetime of a mission, avoiding natural decreases in performance and adaptability to changing mission requirements.
With up to 20 programmable channels, which can be custom programmed, this solution has been designed for ease of use and offers transmit and receive frequencies covering both amateur and commercial bands. The flight proven TRX-U is an ideal satellite TT&C Radio or Narrow Band Communication Payload for CubeSat and SmallSat missions.
These units have been extensively tested and are in use by clients around the world. They have been deployed on orbit in various configurations for close to two decades of successful operations.
Frequencies
With UHF uplink & downlink the TRX-U serves both the commercial and amateur frequencies respectively
Custom Configuration
The firmware of the component is changeable on-orbit enabling upgrades over the lifetime of a mission, thus avoiding natural decreases in performance. With up to 20 Channels, which can be custom programmed in 1KHz Steps. With transmit/receive data rates of 2.4 and 19.2 Kbps this solution is highly adaptable to meet your mission needs
