Özet

© 2021, Univelt Inc. All rights reserved.Sequential orbit determination using angle and range measurements for geostationary satellites is presented. The approach includes position, velocity and bias estimation with Unscented Kalman Filter. The measurements are taken from the actual ground station antennas at TURKSAT. In order to evaluate the accuracy and the robustness of the system, estimation is repeated with single and multiple ground station measurements for satellite T4B. Estimation results are compared with the reference orbit determination software and a very good agreement is obtained.
