Abstract
A system for navigating a mobile object generates satellite navigation data for the mobile object based on satellite navigation signals received from a plurality of satellites and base data received from a stationary base station. The satellite navigation data for the mobile object includes code phase estimates and carrier phase estimates for the plurality of satellites. The system computes position, velocity and time estimates for the mobile object in accordance with the code phase estimates and carrier phase estimates, and performs a navigation function for the mobile object in accordance with the computed position, velocity and time estimates for the mobile object. The system generates the code phase estimates by performing a Vector Delay Locked Loop (VDLL) computation process, and generates carrier phase estimates for the plurality of satellites including by performing a Real-Time-Kinematics Vector Phase Locked Loop (RTK-VPLL) computation process.
