What does RS stand for?

According to the paper, "Non-Keplerian Orbits Using Low Thrust, High ISP Propulsion Systems," an innovative solution to the Mars communication problem may be found by placing a pair of communication relay satellites into a very special type of orbit near Mars: a so-called 'B-orbit'.

The Tracking and Data Relay Satellite, or TDRS, K program successfully completed a design review at NASA's White Sands Complex in New Mexico.

Wide-ranging applications and their theoretical bases discussed include a multimode traffic assignment model considering emissions under various engine operating modes, a tracking and data relay satellite simulator to test antenna control systems, three-dimensional object-oriented geological modeling, and the Systems Dynamics model of a product marketing system.

For more than six months, live pictures - from manned spy aircradft and drones - have been broadcast through Telstar II, a commercial TV relay satellite over Brazil.

Last summer, its insurance carrier refunded as much as $32 million to NASA after the main antenna on a next-generation Tracking and Data Relay Satellite performed well below specifications.

Columbia controls and operates the commercial C-Band capacity on board two satellites in NASA's Tracking and Data Relay Satellite System (TDRSS).

The United States Tracking and Data Relay Satellite System (TDRSS), which has linked the Space Shuttle and Landsat 4 to a ground station, is an example of such a system.

Further expansion on these services will be provided by RCA in support of the operation of NASA's Tracking and Data Relay Satellite System (TDRSS) in 1982.
