Comparison of the Russian and Us algorithms for catalog maintenance for geosynchronous satellites Conference Paper uri icon


  • For catalog maintenance of geosynchronous satellites the US uses an analytic theory (SDP4) based on Brouwer's theory and Russia uses a semi-analytic theory that contains more terms of the geopotential. In this paper the performance of the two algorithms for predicting the motion after fit spans of 30, 60, 120 and 365 days is compared for five satellites.
