TECHNICAL ASSESSMENT OF SATELLITES FOR CONUS AIR TRAFFIC CONTROL. VOLUME II: RANDOM ACCESS AIRCRAFT-TO-SATELLITE TECHNIQUES

A number of satellite system techniques have been suggested as candidates to provide ATC surveillance, communication, and/or navigation service over CONUS. All techniques perform position determination by multilateration using a constellation of satellites. They can be categorized as follows: (1) Coordinated Aircraft-to-Satellite Techniques (CAST), (2) Random Access Aircraft-to-Satellite Techniques (RAST), (3) Satellite-to-Aircraft Techniques (SAT). A technical assessment is made of the various techniques with no one particular technique emerging as superior; several feasible alternatives are identified. The assessment indicates that satellite based techniques for CONUS ATC can be developed without relying on high risk technology. This volume deals with RAST; CAST and SAT are treated in companion volumes. A system employing RAST could operate by having each aircraft transmit a unique signature periodically, without any coordination of transmissions. The position of an aircraft is then obtained by multilateration using the arrival times of its signature at four or more satellites.
