Algorithm for Processing Measurements of a Hybrid Aviation Surveillance System

Abstract

It is shown that a significant disadvantage of the broadcast-type automatic dependent surveillance system (ADS-B) used to solve the problem of aviation surveillance is its vulnerability to spoofing attempts. To eliminate this disadvantage, it is currently proposed to use the monitoring of ADS-B data using multilateration aviation surveillance systems (MLAT). The work shows the necessity of MLAT modernization to ensure a reliable solution to the problem of aviation surveillance in the event of failure of one or more reception points. To do this, it is proposed to use hybrid methods for assessing the coordinates of an aircraft. It can reduce the number of minimum required receiving positions due to the structural and informational redundancy of the aviation surveillance system. Structures (scenarios) of hybrid multi-position aviation surveillance systems and algorithms for processing their measurements have been developed. The algorithms ensure an increase in the reliability of the formation of estimates of aircraft coordinates.
