摘要

Dual-antenna attitude determination technology based on global navigation satellite system can measure the attitude of transporters continuously and accurately. The correct resolution of integer ambiguity is the basis. Integer ambiguity resolution methods with single epoch data for attitude determination are immune to influence of cycle clip and provide attitude determination immediately, but for most methods, the differences are large between the float solution and the correct integer ambiguity, the search space are large, and the validation of integer ambiguity is difficult. For these problems, baseline constrained iteration least square algorithm used the known baseline length which is proposed to improve the float solution; threshold changes step-by-step to reduce search space; the validation of integer ambiguity is accomplished by comparing the calculated baseline vectors using BDS and GPS data after the baseline length validation. The results of actual testing show that the success rate is more than 98 %, the integer ambiguity resolution method can be effectively used for attitude determination with single epoch data.
