With the rapid development of LEO communication constellations, the performance enhancement of existing medium and high orbit constellations has been realized by making full use of the characteristics of LEO communication satellites, such as high transmission rate, low orbit height and large constellation scale, which has attracted extensive attention and become a research hotspot. Based on the systematic analysis of the available resources of the LEO communication constellation, this paper presents a system architecture of navigation augmentation based on the LEO communication constellation. It analyzes the available constellation and frequency resources. The performance of improving the reception sensitivity of BeiDou user terminals and providing emergency backup positioning based on the LEO communication constellation is quantitatively evaluated through theoretical calculation and simulation analysis. The research results can provide a reference for designing and constructing an integrated positioning, navigation, and timing service system.
