Two Line Elements(TLE) is the only publicly available and most complete data sets of Earth orbit objects.The prediction accuracy with SGP4/SDP4 is limited.The TLE+SGP4/SDP4 prediction error sources and improvement method with historical TLE data were analyzed.A pseudoobservation data generation method was introduced.The fitting period of TLE data and the value of At used in generating pseudo-observation are dependent on the orbital altitude.An effective areato-mass ratio(A/M) determination method was obtain...
