摘要
Abstract
When the satellite navigation receiver solves the PVT(Position,Velocity,and Time),the Weighted Least Squares method based on iteration is generally used.However,due to the multiple iterations of this method,the amount of computation is large.In order to solve this problem,this paper proposes a solution.Firstly,a non-iterative PVT solution method is proposed,and an improved non-iterative PVT solution method is proposed to solve the initial value of the positioning result by using the non-iterative method.And then,it uses the traditional iterative solution method to perform an iterative solution.Finally,the receiver using DSP+FPGA architecture is tested and verified.The test results show that the solution accuracy of the proposed method is consistent with the traditional method,but the computational load is reduced by more than 50%.关键词
