Simulation and Analysis for Error from Satellite Capture Segment Anti-spoofing

The anti deception technology of the capture section is put forward, which is based on the idea of three-dimensional space compression domain. In the first part, the acquisition range of the signal is strictly controlled and the difficulty of the attack is increased. Doppler frequency and code phase estimation error are the key factor to affect the performance of the technology. The smaller the estimation error is, the more accurate the position of the real signal can be accurately determined.
