Air-traffic regulating systems

摘要: An improved position-prediction method and subsystem to permit better ground prediction of aircraft future position is disclosed. It proposed for use in air traffic control systems which offer an IPC (intermittent positive control) service all VER carry the not yet standardized DABS beacon (a planned discretely-addressable variant present radar-response beacons include automatic reception display ground-to-air commands). Disclosure proposes that this new should modest cost means report turn rate periodically a string successive radar fixes be data processed with corresponding such reports derive ''''flight-headings'''' are both accurate (due averaging many noisy over seconds time) very current by virtue effectively remove long lag resulting from averaging. The disclosure shows five different methods process so as predict positions based thereon.
