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

In this abstract, it is explained that a mobile device is capable of determining its position using signals received from satellites in a satellite positioning system. However, if there is a disruption in the carrier phase (such as a cycle slip), the mobile device can still generate a continuous carrier phase by using its device history. The device tracks the carrier phase and calculates its position at a certain time. If a cycle slip is detected at a later time, the device resolves the ambiguity in the carrier phase based on the previous carrier phase and position estimate.
