在普通的基线长辅助LAMBDA搜索算法的基础上,提出了一种组合的模糊度搜索方法,确保了单历元算法的成功率和精度。实测数据的计算结果表明,本文所采用的单历元算法无论在静态还是动态情况下,都可以得到很高的成功率和很好的定向精度,也说明本文的实时单历元定向算法是可靠的,方案是可行的。
Starting from the common LAMBDA algorithm with baseline length constraint,a combined 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 of several groups of GPS data indicate that the single epoch algorithm with dual-frequency data can get very high success rate and heading accuracy,and demonstrate that the GPS heading determination algorithm is feasible and reliable in practice.
