METHODS AND APPARATUS FOR CARRIER PHASE CONTINUITY IN SATELLITE POSITIONING SYSTEM SIGNALS: abstract simplified (17698731)

The abstract describes a mobile device that can determine its position using signals from satellites in a satellite positioning system. If there is a disruption in the carrier phase of the signals, such as a cycle slip, the mobile device can use its history to generate a continuous carrier phase. The device tracks the carrier phase and calculates a position estimate. If a cycle slip is detected, the device resolves the ambiguity in the carrier phase based on the previous position estimate.
