Some research on Beidou dual-frequency wide lane combination ambiguity solving

In view of the key technology of solving ambiguity of high precision move positioning, based on the traditional LAMBDA method of ambiguity solving, this passage improve and put forward a double-frequency observation model calculating ambiguity wide lane. Combined with the observation model and partial data, through self-programming for any four Beidou satellites wide lane ambiguity and satellite ambiguity solving process was simulated. The simulation results show that on the one hand, double-frequency wide lane portfolio model can be effectively applied to the fixed ambiguity, on the other hand, the ambiguity of solving process of the high reliability.
