Problems solved by technology

However, the UAT data link is not equipped to receive or send Mode S extended messages
[0010] Although many small aircraft and range jets are equipped with radar transponders, they are not equipped to broadcast Mode S Extended Messages
Also, while most commercial airliners are equipped with Mode S transponders, most are not equipped to broadcast signals using the UAT format
therefore, the mixture of airborne equipment of different aircraft still poses a challenge to air traffic control and monitoring systems

Embodiment Construction

[0036] Referring now in more detail to the drawings, wherein like numerals represent like elements throughout the views, figure 1 A ground-based transceiver system 110 including a universal access transceiver (UAT) system 210 and a module 10 according to one embodiment of the present invention is described. UAT system 210 provides a radio data link for ADS-B signals, FIS-B signals, and TIS-B signals. With the module 10 installed, the transceiver system 110 of the present invention can also provide a radio data link to transmit the data contained within the Mode S extended text signal to a vehicle having a UAT data link system. Although position signals are generally described in this application as being received from or sent to aircraft, it should be understood that the present invention can be used to process signals from any type of vehicle or station, and to broadcast signals to any type of vehicle. An appropriately equipped vehicle or station.

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...
