【Abstract】 Based on the orbit determination theory,the problem of orbit accuracy of collocated geo stationary satellites is discussed.Effects of system dynamics biases on orbit determination and prediction are studied in detail mainly by computer imitation method.Thus the limits of main biases are obtained and some suggestions about orbit calculation and tracking method of collocated geo satellites are given in order to improve the accuracy of the relative satellite position determination.更多还原
