Comparison of Non Iterative and Iterative Algorithms with Pseudo Range Double Difference
摘要
Abstract
Aiming at the problem of the least square iterative algorithm with low positio‐ning efficiency w hen it has no initial coordinates or it has poor initial coordinates in the global positioning system ,the Pseudo range double differential non iterative algorithm was pro‐posed .In this paper ,the principle of these two kinds of location algorithms was discussed u‐sing Pseudo range double differential positioning and tested using observed date .According to the results ,the positioning accuracy and efficiency of these two algorithms were analyzed and compared .It concluded that using the approximate coordinates of the receiver calculated by the non iterative algorithm as the initial value of the least square iterative algorithm can improve the positioning accuracy and running efficiency of the iterative algorithm w hen there are no initial coordinates or the initial coordinates are poor .关键词
