Abstract

The article presents the concept and the structure of the localization module. The prototype module is the part of the VCS (VCS-MLAT) localization distributed system. The device receives the audio signal transmitted in airplanes band (118 MHz – 136 MHz). Received data with the timestamps are send to the main server. The data from multiple devices estimates the localization of the airplane. The main aim of the project is the analysis of the innovative airplane localization method in the close to real environment, based on the audio signal transmitted in 118 MHz – 136 MHz band. The development work requires elaboration and implementation of the prototypes of the distributed system. This concept will increase security in civil and military aviation in the situation when the rests localization systems failed. The localization module as a part of the VCS localization system contains: motherboard with System on Chip integrated circuit, analog radiostation, GPS receiver and ADS-B receiver. The audio signal received from radiostation is sampled and send with the timestamps synchronized by the GPS module to the main server. Moreover, the verification of proper working VCS-MLAT system will be provided by ADS-B receiver. The special software in the main VCS system server is responsible for the estimation of aircraft position with the cooperation of dedicated localization modules, which are placed on monitored area. The concept of radiolocalization system based on the VCS communication structure should be considered as unique, compared to actual systems.
