Abstract

A surveillance transceiver system is provided for receiving extended squitters from Mode S transponders, translating the squitters into ADS-B state vectors in UAT format, and transmitting the ADS-B state vectors using a Universal Access Transceiver (UAT) datalink. The surveillance transceiver system bridges the gap created by differently-equipped aircraft by using multiple datalinks to provide seamless ADS-B surveillance. The module for processing the extender squitters includes a 1090 MHz receiver and a computer processor in communication with the UAT processor for parsing the squitter and composing the ADS-B state vector in UAT format for broadcast.

Description

technical field

[0001] This invention relates generally to the fields of avionics and surveillance transceiver systems. More particularly, the present invention relates to a method, apparatus, system and computer software product for receiving an ADS-B message and converting it from Mode S format to UAT format for use with a Universal Access Transceiver (Universal Access Transceiver) to broadcast. Background technique

[0002] Historically, air traffic control systems have relied on a network of ground-based radar stations and transponders onboard each aircraft. In response to a radar beacon interrogation from a ground station, the transponder broadcasts a response. This transponder signal provides basic information about the aircraft to air traffic controllers. The transponder sends a four-digit octal code and the flight altitude of the aircraft (Ownship). The position of the aircraft is inferred by measuring the moment of reception and the angular position of the radar...
