摘要：

Orbit position uncertainty is an important factor for collision avoidance issues. Fora single object with high frequency historical data, we can attain its position uncertainty easily. But sometimes data is not enough for errors analysis, orbits need to be classified. In this paper error analysis is made from two-line element sets data (TLEs). The Simplified General Perturbations-4 (SGP4) propagator wits used. Statistical errors of debris and R/B are given for lower-altitude orbits which arc classified by perigee altitude and eccentricity. The errors results and analysis for SSO (the Suit synchronous orbit) typical orbits arc obtained. At last atmospheric drag as a main cause of downrange errors in lower-altitude orbit is analyzed. BSTAR in TLEs is modified to improve prediction precision. (C) 2008 COSPAR. Published by Elsevier Ltd. All rights reserved.
