The navigation receiver simulation and estimate software system design

Abstract

Developing the satellite positioning and navigation system independently is a huge project. Establishing the simulation and estimate software system for navigation receivers can supply reference data for developing and improving real receivers. This paper analyzed the general structure of the receiver, presented a more feasible design method for the receiver simulation and estimate software system, introduced some estimate items and the data or algorithms which the items needed, and proposed a solution to C/A code rapid acquisition with inertial navigation system (INS) assisting. This software system consists of a signal simulator, a navigation receiver simulator and a receiver estimate software and is based on MATLAB/SIMULINK. It helps to configure a precise receiver simulation and estimate system.
