Abstract

The invention discloses a method for building a satellite navigation system test verification and test assessment mathematic model. The method comprises the steps of S1: driven by function and performance verification / assessment of verification, design, construction and application stages of a satellite navigation system, determining a verification / test and assessment project of the satellite navigation system, and forming a verification / test and assessment method for a to-be-tested item; S2: according to driving data, determining a satellite navigation physical system or entity generating the driving data; performing abstraction on a satellite navigation physical system entity / function to form a system level simulation model, wherein the model is a basis of a satellite navigation system test verification and test assessment mathematic model system; and S3: after a satellite navigation system verification / test and assessment model and the system level simulation model are built, performing self-closing verification, and performing abstraction on self-closing verification item and method to form a self-closing verification model. The method has the advantages of simple principle, easy realization, good effect and the like.

Description

technical field [0001] The present invention mainly relates to the field of satellite navigation systems, in particular to a method for establishing a mathematical model for satellite navigation system test verification and test evaluation, mainly to solve the problem of global navigation satellite system (Global Navigation Satellite System, GNSS) in the construction and maintenance phases of the system. The main business, information interface, simulation test and evaluation of key stand-alone machines can also be used to build a satellite navigation ground test system. Background technique [0002] The satellite navigation system is generally composed of three parts: the space segment, the ground segment and the user segment, and its construction is a long-term and complex system engineering. During the construction of the satellite navigation system, in order to verify the new technical system and shorten the joint debugging and testing cycle of the ground operation contr...
