Laboratory Design and Management Principles, support for constructing the future PNT system and improving its service performance. Spoofing is a potential factor to affect reliability of GNSS services, LEO satellites can provide reliable information as independent navigation sources and show good anti-spoofing performance with dual-direction

Determination of 131I in Water,are important factors affecting the reliability of airborne satellites navigation system. LEO satellites with advantages of running in low orbits, having rapid change of satellite geometry and strong anti-interference capability of satellite signal, can significantly enhance the credibility of BDS.

To solve this dilemma, a loose coupled RTK/INS positioning method based on robust estimation is proposed. Firstly, during RTK positioning, for eliminating corrupted measurements caused by Non-Line-of-Sight (NLOS) signals and multipath, this p

Considering the needs of communication services, the integrated signal generally has burst characteristics, and the receiver only receives the signal from the satellite in some specific time slots, and the observation has obvious asynchronous arrival characteristics. Such a

Then, the interference evaluation method based on the spectral separation coefficient is used to quantitatively evaluate the attenuation of c
