Patent number: 10534087Abstract: A method for enhancing GPS location accuracy includes providing a base station receiver having a known surveyed location, and a roving receiver at a location distinct from the base station receiver. The method further includes receiving single-frequency code and carrier-phase measurements from the base station, and translating the single-frequency code and carrier-phase measurements to a Kalman filter-predicted location of the roving receiver. The translated single frequency code and carrier phase measurements are used to generate a local replica of the Kalman filter-predicted location signals for each channel of the roving receiver. The method further includes correlating the local replicas with an incoming signal of the roving receiver to generate a plurality of tracking error estimates. The plurality of tracking error estimates are used to update navigation states and clock update states thereof.Type: GrantFiled: May 31, 2016Date of Patent: January 14, 2020Assignee: United States of America as represented by the Secretary of the Air ForceInventors: James J Brewer, John F Raquet
