Application of ADS-B for Providing Surveillance at Civil Aviation Regional Aerodromes

Automatic Dependent Surveillance-Broadcast is an inexpensive promising technology that can ensure the required surveillance quality. This technology, however, has some shortcomings and vulnerabilities due to which the ICAO insists on confirming the ADS-B data by other surveillance tools, including radars and multi-position systems, which can increase surveillance infrastructure costs. For regional Russian aerodromes, particularly those located in the Arctic zone, the economic component is crucial. The task to conduct observations using the ADS-B stations and alternative coordinate confirmation methods is urgent. The article provides an overview of methods employed in the algorithmic confirmation of ADS-B data reliability based on estimating mathematical expectation and standard deviation (for different levels of reliability) of normally distributed aircraft positioning errors. The gating method, which involves selecting an area around the extrapolated aircraft coordinate, is proposed. The methodology can be applied to describe the ground and air traffic in the working area of aerodromes and the aerodrome area.
