Space Ground Transmitter Receiver Controller
The Space-to-Ground Subsystem is a key communications structure for the International Space Station. Our Transmitter/Receiver/Controller and Space-to-Ground Antenna are mounted on the outside of the station and provide high-rate data communication with the ground.
- 600 Mbps – Rate of data transmission to the ground
- 0.5 – Degree of accuracy at which the system must target the Relay Satellite to transmit data
- 12-18GHz – Spectrum for the Ku-band satellite frequency used by the subsystem
- 6 months – Average length of time ISS crew are away from family and friends
