| Abstract: | To solve the deviation of angle measurement data about multi-target orbit determination in spread spectrum mode,this paper proposes an angle correction method based on multi-target angle error voltages after analyzing its defect. According to this method,actual tracking data is analyzed and the inversion checking for orbit determination is completed by correcting actual angle measurement data. Results show that real-time angle correction through improving the transmission mode of multi-target angle measurement information can increase the multi-target measurement accuracy in same beam. |
