An Asynchronous Observation Positioning Algorithm Based on Factor Graph Optimizationion is an existing trend. 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

Impact of Temporally Correlated Error on ARAIM ISM During Ionospheric Storm Periodect the performance of satellite navigation. Therefore, civil aviation standards require that the impact of ionospheric anomalies (especially ionospheric storms) should be considered in integrity monitoring. To meet the safety requirement of satellite navigation service in civil aviation, it is urge

Scintillation Identification Based on Spectral Featuresvarious features on scintillation variation. Different methods can be developed with ML to find out potential scintillation impacts, and satisfied results generally could be arrived with accuracy of 95%. It also point out that the descending trend existed over Fresnel frequency is essential to disti

Impact Analysis of BeiDou Satellite Integrity Events in 2022u System will become the focus of global civil aviation users. During the assessment of the BeiDou open service performance, it was found that in March 2022, the BDS- 3 MEO-3 (PRN21) satellite had a serious abnormal event. The event occurred in which PRN21 satellite had a frequency offset fault of t
