Precise positioning using GPS carrier phase measurement has been widely used in static applications. However, it can also been applied to precise positioning of a moving platform if ambiguities contained in the GPS carrier phase measurement are resolved during the motion. Precise positioning of a ship is especially difficult due to the high dynamics of the antenna and the high reflectivity of the water. However, marine application can use altitude aiding to help significantly in resolving the ambiguities. In this paper, a new approach for ambiguity resolution method using altitude aiding and wide-lane search before stepping to L1 ambiguity search technique in the marine environment is investigated. The algorithm has been tested in Tokyo Bay. The ambiguity fixed percentages are 95.3% without altitude aiding and 97.5% with altitude aiding. The time to fix is almost single epoch with altitude aiding.
