变粒度搜索算法与整周模糊度解算
Searching algorithm with granularity changing and GNSS integer ambiguity estimation
摘要
Abstract
The traditional algorithm of GNSS orientation using LAMBDA for single frequency receiver,can't estimate the integer ambiguity in a little time,sometimes,can't find the exact value.Based on the theory of rough integer mapping,a new algorithm for the estimation of integer ambiguity is presented to solve the problems.Searching algorithm with granularity changing can im-prove the searching efficiency of the integer ambiguity,and can deal with the problem of the GNSS carrier phase measurement in real time.关键词
