A Correlate-Based GPS Multipath Time Delay Estimation Algorithmkes the correlation output of received signal correlates and the local C/A code as the model, estimates the direct signal and the multipath signal delay accurately in the condition of signal delay is unknown. As can be seen from the simulation results, the multipath interference suppression algorith

Simulations and Analysis of BeiDou Navigation Satellite System (BDS)-Relectometry Delay-Doppler Mapsn DDM simulations from BDS-R, while the vegetation scattering properties are simulated using the modified Bi-mimics model, which can be used to calculate any transmit and receive polarization combinations, assuming that the received power is coming from the first Fresnel zone. The theoretical simula

Earth Rotation Parameter Estimation from GNSS and Its Impact on Aircraft Orbit Determinationan achieve at 0.0283 and 0.0289?ms when compared to IERS C04 solutions, respectively. The precision of PM and LOD from regional stations with daily GPS (GLONASS) observations are better than 0.178?mas (0.365?mas) and 0.0291?ms (0.0360?ms), respectively. The precision of PM and LOD from combined GPS+
