The Testing of MLAT Method Application by means of Usage low-cost ADS-B Receivers

Abstract

The paper describes the process and results achieved during the measurement which was realized with the aim of identify an applicability of MLAT (Multilateration) method by means of using so-called "low-cost" ADS-B receivers. In terms of measurement, ADS-B receivers without GPS time synchronization module was utilized thus specific time synchronization method was required to implement.

Voice Multilateration System

“…These technical specifications set out minimum performance requirements for those systems that provide air traffic controllers with real-time information on the airspace situation. The results of the practical verification of aircraft location accuracy in MLAT systems available in the literature concern solutions in which the source of signals for distributed reference stations are SSR and ADS–B systems [ 14 , 15 , 16 ]. However, the synchronization of individual reference stations is performed using GPS receivers [ 17 , 18 ].…”
