SpaceRef - Astronautics - Communication - TDRSS

TDRSS Tracking and Data Relay Satellite overlook - When first launched, the TDRS satellites were the largest, most sophisticated communications satellites ever built. The seventh vehicle in the series was ordered as a replacement when TDRS-2 was lost in the Challenger accident. This page at NASA Jet Propulsion Laboratory provides an overview of the system.

Tracking and Data Relay Satellite System (TDRSS) - TDRSS is a communication signal relay system which provides tracking and data acquisition services between low earth orbiting spacecraft and NASA - customer control and/or data processing facilities. The system is capable of transmitting to and receiving data from customer spacecrafts over at least 85% of the customer's orbit. NASA Goddard Space Flight Center.

Tracking and Data Relay Satellite System (TDRSS) spacecraft locations - Currently the TDRSS has six spacecraft in orbit. This page provides a table that gives the location of these satellites. NASA Goddard Space Flight Center.

Tracking and Data Relay Satellite System Description - This page at NASA's Network Control Center describes the earth stations used to communicate with the TDRSS.
