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.
Bridging the divide
The system can handle standard and high definition video and transmit pre-recorded messages or live, two-way conference calls. This is used to communicate with the Mission Control Center in Houston and transmit scientific data. More importantly, it lets crew members contact their families back here on Earth.
