A number of satellite system techniques have been suggested as candidates to provide ATC surveillance, communication, and/or navigation service over CONUS. All techniques determine the aircraft positions by multilateration based on the arrival times of signals transmitted between the aircraft and the satellites. The techniques can be categorized as follows: (1) Coordinated Aircraft-to-Satellite Techniques (CAST), (2) Random Access Aircraft-to-Satellite Techniques (RAST), and (3) Satellite-to-Aircraft Techniques (SAT). This volume summarizes the results of a technical assessment of all three techniques. The detailed assessment is presented in companion volumes. The assessment has shown that workable systems could be configured using any one of the three techniques without reliance on high risk technology. No one technique has emerged as superior. Rather several viable alternatives have been identified. All techniques appear to require more costly avionics than today's ground-based system.
