Atomgewicht und Lebensdauer der Isotopen,ong anti-interference capability of satellite signal, has become an important development trend of satellite navigation enhancement. In view of the problems such as weak landing signals of BeiDou-3 Navigation Satellite System (BDS-3) and vulnerability to external spoofing, combined with the potentia

Protection Level for Precise Point Positioning Based on Gaussian Mixture Modelcan better de-scribe the non-Gaussian feature of the observation noise. In the suburban scenario, the HPLs and VPLs based on GMEKF are reduced by 33.6% and 33.1% compared with Kalman filter respectively, so as to improve the availability of the PPP integrity monitoring algorithm.

Multi-parameter Characterization of Ionospheric Disturbances Based on GNSS Ground-Based CORS Data (MSTIDs) using the U.S. CORS navigation ground station. The MSTID occurring at 4:30 UT–4:45 UT was verified by data from the U.S. CORS stations on July 20, 2006, and the tomography results showed a clear perturbation trend in the electron density at altitudes of 100 to 220 km. It is demonstrated th
