Performance of GNSS Global Ionospheric Modeling Augmented by LEO Constellation by Xiaodong Ren, Xiaohong Zhang, Michael Schmidt, Zhibo Zhao, Jun Chen, Jincheng Zhang, Xingxing Li

“…In this paper, we present the performance and accuracy of global ionospheric model augmented by LEO constellation for the first time. Based on the three kinds of designed LEO constellations with 60, 96, and 192 satellite simulation data, the results show that LEO observations can expand the coverage and increase the density of ionospheric pierce points (IPPs). …”

Single-Satellite Integrated Navigation Algorithm Based on Broadband LEO Constellation Communication Links by Lvyang Ye, Yikang Yang, Xiaolun Jing, Jiangang Ma, Lingyu Deng, Hengnian Li

“…Finally, for different scenarios, we conduct qualitative and quantitative analysis through simulations, and the results show that, whether in an altimeter scenario or non-altimeter scenario, the performance indicators of our algorithm are significantly better than the inertial navigation system (INS), which can effectively overcome the divergence problem of INS; compared with the medium earth orbit (MEO) constellation, the navigation trajectory under the LEO constellation is closer to the real trajectory of the aircraft; and compared with the traditional algorithm, the accuracy of each item is improved by more than 95%. …”
