Abstract

This invention discloses one method based on Big double star system rapid measurement pose, which comprises the following steps: at initial time t0, putting antenna one and two along the measurement direction needed to get the vector r(t0) length L and t0 first set load wave phase observation values; changing the original moving base line length as k1 times along base line direction to get the newvector k1r(t0) to get second set of load wave phase valuesDeltphi<112(t1),Deltphi<212(t1); getting several groups of observations to get the direction angle phi and pitching angle thetato fulfill the measurement.

Description

1. Technical field

[0001] The invention relates to a method for measuring the attitude of a carrier, in particular to a method for measuring the carrier by using the Beidou double star system. 2. Background technology

[0002] The attitude measurement under the Beidou dual-star system is an important application field of the Beidou navigation system. The attitude is obtained by solving the receiver antenna baseline vector in the navigation coordinate system through the satellite carrier phase information. The core problem is the solution of the ambiguity of the whole circle. Due to the small number of satellites in the current Beidou navigation system, it is difficult to implement the method of solving the ambiguity of the whole circle commonly used in the GPS navigation system, such as the least square search, under the Beidou dual-star system. At present, the attitude measurement methods and related systems developed in China use the rotating baseline (Lu Liangqing, Hu Xia...
