Design of multi-channel distrubion system in high-precision test system for navagation users

This paper presents a multi-channel user device test system distribution plan, and develop a channel using the least squares method to adjust the consistency algorithm to solve the multi-channel low-power test channel consistency weak signal conditions for the protection of large quantities of user equipment performance indicators comprehensive, efficient, reliable, fair, equitable, high-precision testing and evaluation, and has begun to put into application. This paper first describes the principles and methods of the satellite navigation and positioning. And simulation analysis to determine the feasibility of navigation test system multiple user devices assigned. Then propose a recursive optimization algorithm to adjust the consistency of the channel, and achieved good effect in the practical application.
