[Abstract]:In order to solve the problem of fast resolution of integer ambiguity in GNSS attitude determination, a short baseline integer ambiguity resolution method based on combined carrier phase is proposed. The integer ambiguity is solved by using the observation data of a single epoch. Based on the results of integer ambiguity resolution of single frequency carrier phase of multiple satellites, the baseline vector is solved accurately by using the least square principle, and then the attitude angle of the aircraft is determined from the baseline vector. The simulation results show that the ambiguity resolution method can solve the integer ambiguity of the carrier phase of at least 8 satellites in a single epoch and solve a key problem in the field of GNSS dynamic attitude determination. The results of attitude determination show that the errors of yaw angle and pitch angle are less than 0.2 擄. The research results can create conditions for the application of GNSS attitude determination system in aeronautics and spaceflight.
