Method and apparatus for improving utility of automatic dependent surveillance
First Claim
1. A system for re-transmitting position data for a plurality of aircraft, the system comprising:
- means for receiving aircraft position data from a broadcast aircraft position system, the aircraft position data received in a predetermined format from each of a corresponding aircraft equipped with the broadcast aircraft position system;
means for determining whether a transmission from the broadcast aircraft position system generating the aircraft position data may be blocked to another aircraft;
means for generating broadcast aircraft position system data in the predetermined format for an aircraft whose transmission from the broadcast aircraft position system may be blocked; and
means for transmitting the broadcast aircraft position system data in the predetermined format for aircraft whose transmission from the broadcast aircraft position system may be blocked to aircraft equipped with the broadcast aircraft position system such that aircraft equipped with the broadcast aircraft position system can determine locations of aircraft whose transmission from the broadcast aircraft position system may be blocked.

Abstract
The surveillance system provides a means to augment Automatic Dependent Surveillance—Broadcast (ADS-B) with “look alike ADS-B” or “pseudo ADS-B” surveillance transmissions for aircraft which may not be ADS-B equipped. The system uses ground based surveillance to determine the position of aircraft not equipped with ADS-B, then broadcasts the identification/positional information over the ADS-B data link. ADS-B equipped aircraft broadcast their own position over the ADS-B data link. The system enables aircraft equipped with ADS-B and Cockpit Display of Traffic Information (CDTI) to obtain surveillance information on all aircraft whether or not the proximate aircraft are equipped with ADS-B.
