For high accuracy positioning, the carrier phase must be used, among the code pseudorange. The carrier measurements are very precise, typically at the level of few millimetres, but contains the unknowns ambiguities, which changes every time that the receiver locks the signal after a cycle slip. Nevertheless, such ambiguities can be estimated in the navigation solution, together with the coordinates and other parameters.
