Design and realization of satellite-based ADS-B signal simulation and display system#br#

Abstract

Abstract: Comparing with ground-based ADS-B, satellite-based ADS-B has the advantages of wider coverage and lower cost but the disadvantages of lower signal power and larger Doppler frequency shift. Through simulation of fourantenna satellite and target trajectory, satellite-based ADS-B signal power and its Doppler frequency shift are calculated. The corresponding software system is developed, which can simulate the Doppler frequency shift and signal power received from target, realizing display of satellite coverage, background map and target trajectory, as well as the digital communication with slave computer.

Key words: satellite-based, power, Doppler frequency shift
