Abstract
A navigation system for a mobile object generates 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 navigation data 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 position, velocity and time estimates. The system generates code phase estimates by performing a Vector Delay Locked Loop (VDLL) computation process that drives a code NCO for each channel of a plurality of channels, and generates carrier phase estimates for the plurality of satellites by performing a RTK Vector Phase Locked Loop computation process that drives a carrier NCO for each channel.
