dc.description.abstractThis Satellite operators rely on accurate satellite orbit estimation to ensure safe orbital operations, considering the influence of external forces. Traditional methods, such as single station angles and range (AZEL), along with range-to-range (RNG) techniques, have been widely employed by operators. However, the use of GPS signals for determining the orbits of geostationary communication satellites (GEO) has gained popularity due to its effectiveness. Extensive research has validated the reliability and efficiency of GPS-based GEO orbit determination. In this study, the performance of the GPS-based method is evaluated by comparing it with flight- proven techniques. Three GEO communication satellites located at different longitudes were analyzed using GPS- based, RNG-based, and AZEL-based methods. The results indicated that the GPS-based determined orbit had a root mean square error (RMSE) of 75.887 m, 372.420 m, and 768,223 m for Satellites A, B, and C, respectively, when compared with the RNG-based determined orbit. Similarly, the RMSE between the GPS-based and AZEL- based determined orbits was 133.287 m, 242.076 m, and 764.866 m for Satellites A, B, and C, respectively. These findings strongly support using GPS-based orbit determination, as it aligns with the results obtained from flight- proven RNG and AZEL methods. The study demonstrates the reliability and accuracy of the GPS-based orbit estimation method. Consequently, it encourages satellite operators to adopt GPS-based navigation for precise determination of communication satellite orbits. The comparison between AZEL vs. GPS and RNG vs. GPS methods reinforces the advantages of utilizing GPS-based navigation.en_US
