RISGPS/Galileo/LEO Uncombined and Ionosphere-Free Combined Precise Relative Positioning and Its Performance Analysis
Publisher: American Society of Civil Engineers
Abstract: The advantages of low-Earth-orbit (LEO) satellites, such as their high signal strength and rapid geometric changes, provide important opportunities for fast, accurate, and robust precise relative positioning (PRP), especially ...
Improved Method for Estimating the Ocean Tide Loading Displacement Parameters by GNSS Precise Point Positioning and Harmonic Analysis
Publisher: American Society of Civil Engineers
Abstract: Site displacements caused by ocean tide loading (OTL) can reach more than several centimeters vertically, particularly in coastal regions. An ocean tide model typically is used to correct OTL effects, but these model ...
Reliable Atmospheric Correction Generation Method for Out-of-Network PPP-RTK Users
Publisher: American Society of Civil Engineers
Abstract: Precise point positioning–real-time kinematic (PPP-RTK) technology can achieve accurate regional positioning with precise atmospheric corrections. However, traditional PPP-RTK algorithm research has focused on users in a ...
