OpenGL Based Simulation Test Bed for Aircraft Ground Telemetry System using Antenna Beam Forming

Abstract

A simulation test-bed based on OpenGL graphics tool is developed for studying the telemetry communication link of aircraft with ground station. The smooth aircraft movement has been implemented using cubic spline algorithm and antenna beamforming algorithms has been used to track the aircraft movement by estimating the AoA (Angle of Arrival). The paper compares the performances of LMS (Least Mean Square) and RLS (Recursive Least Square) antenna beamforming algorithms to track the movement of aircraft in the presence of noise. The simulation test-bed was able to track the aircraft movement successfully for AOA of less than 75° with signal to noise ratio of more than 4dB.
