Precise orbit determination is an essential task for analyzing satellite laser ranging (SLR) data. The quality of the satellite orbits directly depends on the background models used for dynamic orbit determination, e.g., on the underlying model of the Earth’s gravity field. We investigate the influence of more than ten recent and well known gravity field models on the quality of a combined LAGEOS-1 and LAGEOS-2 orbit determination by analyzing orbital fits. For this purpose we process the SLR… CONTINUE READING
