WebOct 23, 2003 · In the GPS literature there are two of the many different approaches proposed for integer ambiguity estimation, which have drawn much interest. The two approaches differ in the model used for integer ambiguity estimation. In the first approach, which is the common mode of operation for most surveying applications, an explicit use WebThe classic approach generally consists of three steps: a float solution, a search for integer ambiguities, and a fixed solution. The new approach is based on certain properties of ambiguity function method and ensures the condition of integer ambiguities without the necessity of the additional step of the integer search.
