Abstract

A mobile device supports carrier phase based positioning using positioning signals received from positioning signals from a plurality of satellites in a satellite positioning system (SPS). In the presence of a discontinuous carrier phase, e.g., if a cycle slip is detected, the mobile device is configured to generate a continuous carrier phase using the device history of the mobile device. The mobile device, for example, may track the carrier phase of positioning signals and determine a position estimate for the mobile device at a first time. If a cycle clip of the carrier phase is detected at a second time, the mobile device resolves the integer ambiguity in the carrier phase at the second time based on the carrier phase and position estimate for the mobile device from the first time.
