Performance Analysis of BDS-3 Klobuchar Models the legacy B1I and B3I signals. With the opening of BDS-3 global service, the service area of the broadcast Klobuchar model (BDSKlob) parameters expanded from China and parts of the Asia-Pacific region to the whole world. In this study, the differences between the GPS Klobuchar model (GPSKlob) and

Real-Time Kinematic Orbit Determination of GEO Satellite with the Onboard GNSS Receiverhronization. For high earth orbit spacecraft, the space environment is very challenging for GNSS receivers to work. Taking the No. 2 Telecommunication Technology Test satellite (TTS-2) as an example, under both preprocessing strategies of the carrier phase smoothing pseudorange algorithm and single

Effect of Troposphere Parameter Estimation on BDS PPPX stations are selected over 24 days for static PPP using four parameter estimation methods: Random walk (RW), Piecewise Constant estimation (PWC: 120/180/360, estimated every 120/180/360 min). The results of the tropospheric zenith delay (ZTD) and PPP positioning are evaluated using the ZTD product

Comprehensive Analysis of the Cycle Slip Detection Threshold in Kinematic PPP During Geomagnetic Sto paper analyzes the BDS/GPS kinematic Precise Point Positioning (PPP) accuracy during the November 2021 geomagnetic storm to investigate the impact of the cycle slip (CS) detection on positioning accuracy under an active ionosphere. The results show that when using the conventional constant threshol
