Abstract:
The study presents an analysis of the orbit determination process for maintenance of the space object catalogue. After quantifying the uncertainties in optical and radar measurements, the second part of the study presents the error within the mean element orbit determination procedure. A batch least square orbit determination method which makes use of the Draper semi-analytical satellite theory and its partial derivatives is tested for its correctness under catalogue maintenance conditions. Different attributes, which could affect the performance of such an orbit determination method, are identified and examined with real and simulated observations. In conclusion, the factors which limit the practical accuracies of the orbit determination procedure are discussed.
