Abstract

Real-time GNSS orientation determination is valuable in many fields. In order to achieve high accuracy orientation with GNSS, the difference carrierphase observation must be employed. The carrier-phase measurements are affected by integer ambiguities, which must be resolved in order to take advantage of the high carrier-phase measurement precision. The information of the baseline length is exploited to reduce the correlation of ambiguities. So the size of integer ambiguities search space can be reduced. In order to make float ambiguity uncorrelated completely, float transformation matrix is constructed by Cholesky decomposition, so the speed of integer ambiguities searching can be improved. The experiment shows the method can improve the speed of integer ambiguities searching.
