摘　　要：在进行北斗单频单历元定向解算时,采用LAMBDA方法获得的最优解不能保证完全正确。在此基础上,本文提出了一种基线长辅助搜索算法,通过理论分析和试验验证,表明该定向算法能够提高单历元定向的成功率和精度。In the single-epoch heading determination algorithm of single frequency BDS,LAMBDA algorithm can not ensure an absolutely correct optimum solution.On this basis,starting from the common single frequency LAMBDA algorithm,a baseline length constraint search method of ambiguity resolution is put forward,which enhances the success rate and reliability and ensures the validity and usability of the single epoch algorithm.The results of calculation indicate that the single epoch algorithm can get very high success rate and heading accuracy,and demonstrate that this heading determination algorithm is feasible and reliable in practice.
