With the rapid development of multi-constellation Global Navigation Satellite Systems (GNSSs), satellite navigation is undergoing drastic changes. Presently, more than 70 satellites are already availa...
Non-Linear Filtering for Precise Point Positioning GPS/INS integration
GPS PPP INS EKF UKF PF and tightly coupled
2014/11/28
This research investigates the performance of non-linear estimation filtering for GPS-PPP/MEMS-based inertial system. Although integrated GPS/INS system involves nonlinear motion state and measurement...
Receiver Widelane Analysis and Its Effect on Precise Point Positioning
Precise Point Positioning Widelane Bias Hardware Delay Ambiguity Resolution
2014/11/28
Typically, differential carrier-phase-based methods have been used in positioning applications that require high accuracy. The main advantage of differential methods is solving the carrier-phase ambig...
Enhanced model for precise point positioning with single and dual frequency GPS/Galileo observables
GNSS PPP GPS Galileo Single frequency Dual frequency
2014/11/28
This paper introduces a newly developed model for both single and dual-frequency precise point positioning (PPP), which combines GPS and Galileo observables. As is well known, a drawback of a single G...
We discuss the use of some new time transfer techniques for computing TAI time links. Precise point positioning (PPP) uses GPS dual frequency carrier phase and code measurements to compute the link be...
