The traditional algorithm of GNSS orientation using LAMBDA for single frequency receiver, couldnpsilat estimate the integer ambiguity in a little time, sometimes, couldnpsilat find the exact value. Based on the theory of Rough integer mapping, we get a new algorithm for the estimation of integer ambiguity to solve the problems we meet. Searching algorithm with granularity changing could improve the searching efficiency of the integer ambiguity, and deal with the problem of the GNSS carrier phase measurement in real time nearly.
