Market Overview

The data relay satellite system is comprised of continuous real-time communication between low Earth orbit-bound spacecraft and the ground station, as well as satellite communication. A data relay satellite receives communications from a ground station or user spacecraft and relays them to the intended destination through radio-frequency or optical links, depending on the system architecture.

On the international landscape, NASA's Tracking and Data Relay Satellite System (TDRSS) is supporting communication and tracking services for NASA's LEO spacecraft. The European Data Relay System (EDRS) uses laser communication links to relay data from compatible low-Earth-orbit satellites through geostationary relay satellites. Japan and China have developed satellite data-relay and tracking capabilities.
