摘要
整周模糊度快速解算是导航定位接收机实现高精度的动态定位和姿态测量重要保证,对该方法的研究意义重大。介绍了目前常见的整周模糊度快速解算方法,并对这些方法进行了分析和比较。通过比较验证了LAMBDA方法在进行整周模糊度解算过程中的优越性,并重点对LAMBDA方法及其改进算法进行了研究,通过仿真分析可知LAMBDA改进算法可以使搜索时间提高一个数量级,为以后工程应用提供了理论基础。
It is of great importance to investigate fast solving integer ambiguity method, asit is guarantee for a navigation and positioning receiver to achieve high precision dynamic positioning and attitude determination. This paper introduces the common fast solving integer ambiguity method, which ware analyzed and compared. Through the comparison,we confirm that LAMBDA method is superior in the process of fast solving integer ambiguity method, and we improve its algorithms. By simulation analysis, It is found that the improved LAMBDA method makes the search time to improve an order of magnitude ,and this provided theoretical basis for engineering application in the future.
