System acquisition, processing and visualitation of Air Traffic Using ADS-B and IoT Connectivity

ADS-B (Automatic Dependent Surveillance-Broadcast) is a cooperative surveillance technology in which an aircraft determines its position through satellite navigation and issues it periodically, which allows tracking. The information can be received by the ground stations of air traffic control as a complement to the secondary radar system that does not need to receive a signal from the ground to emit. It can also be received by other aircraft to allow knowledge of the situation and allow self-separation. The ADS-B is automatic in that it does not require any pilot action or external input and is in turn dependent, which depends on the data of the navigation system of the aircraft. ADS-B equipment are currently mandatory parts in parts of Australia's airspace, while in the United States and Europe they are part of the aircraft that own these devices by the year 2020. Argentina is governed by ICAO regulations (International Civil Aviation) Organization) and the FAA (Federal Aviation Administration) of the United States, which implies the same application times in Argentina. This paper explains the development of a receiving earth station system and decoder of the ADS-B system using an embedded platform, combining COTS (Commercial Off-The-Shelf) and associated software components. An OrangePI+ board, an SDR-RTL-2832U receiver and a LoRa transceiver were used to distribute the information to remote stations for further processing and visualization in a distributed manner.
