Position error analysis of double satellites optical observation system

In order to improve the positioning accuracy of double satellites optical observation system, a new type of optical positioning system is constructed. Based on the modeling of the satellite and the optical observation platform, the observation vector model between the platform and the target is constructed. According to the geometric location algorithm, the target location model and the location error model are derived, and the location error distribution is obtained by the Monte Carlo method. On this basis, wavelet theory is brought to optimize and reconstruct error for improving the positioning accuracy of double satellites optical observation system. Using the measured data for simulation, the results show that the wavelet theory introduced to reconstruct the position error can make the positioning accuracy increase by 30%. It provides a new way to reduce the location error in engineering.
