%X In this paper, optical target monitoring orbit determination using the Gooding algorithm based on the 400km altitude space platform was researched. The measurement error was set to 3" and 6" respectively for 800km, 1500km altitude low Earth orbits and 36000km altitude geosynchronous orbit to determine the initial orbit and precise orbit. Simulation results show that the initial orbit determination accuracy of the 4~15min arc is about 10km, and the 1~2min arc is about 100km when the measurement data error is between 3" and 6". The error of 15min initial determination arc is 100m. As the arc is less than 10min, the improved error accuracy of the orbit is in the order of km scale. As the measurement data error is 3", the initial orbit determination accuracy of the 15~20min arc is about tens of kilometers, and that of the 8~10min arc is 100km. The improved orbit has an error of km. When the measurement data error is 6", the accuracy of the initial orbit determination of the 20min arc is at the magnitude of 10km, the accuracy of the initial orbit determination of the 8~15min arc is at the magnitude of 100km, and the error accuracy of the improved orbit is at the magnitude of 10km.
