N2 - Because of the need of radio backup navigation, Doppler localization algorithm based on low-orbit constellation is analyzed and simulated. Compared with low-orbit single-star Doppler location, low-orbit multi-star Doppler location is less affected by the initial iteration point, and low-orbit multi-star Doppler location needs to converge in short time. Through the comparative analysis and simulation of multi-star Doppler location of low-orbit constellation and medium-orbit constellation, it is concluded that the multi-star Doppler location is more accurate under low-orbit constellation. At the same time, the more stars can be seen in the process of multi-star Doppler localization, the higher the positioning accuracy is.
