Modeling and Analysis of Orbit Determination of Geostationary Satellites-Based on Active Maneuvers

Abstract

This paper focuses on modeling and analyzing an orbit determination technique specifically tailored to geostationary satellites employing active maneuvers. Active maneuvers involving deliberate orbital adjustments, using Reaction Control Thrusters (RCT) by the onboard propulsion systems, are performed to maintain the desired position and extend operational lifespans. In addition, this paper presents a comprehensive overview of the orbit determination process, encompassing observations and tracking, data processing, dynamic modeling, maneuver planning, orbit determination, and error analysis. The mathematical model is implemented to detect the position of the Geostationary Earth Orbit (GEO) satellite through MATLAB-Simulink. The results provide insights into the difficulties and opportunities in modeling and analyzing geostationary satellite orbits based on active maneuvers. The outcomes of this paper advance satellite operations by enhancing an orbit determination technique. A comparative analysis is conducted with an established satellite platform (Eurostar-3000) using Root Mean Square Error (RMSE) for orbital parameters. Ultimately, the model simulation results validate the proposed methodology's effectiveness.
