Research on Difference Validity of Integrated Long-wave/Microwave Navigation System

Along with the development of system from singularity to integration,different electric waves are integrated organically,a lot of coupling systems come into being,but it results in difficulty of analyzing the difference validity of these systems.In order to improve the precision,a method should be proposed to estimate the validity of difference,because of the influence from the geographical restrictors.So,according to the system between long wave and microwave,this paper firstly put forward the way to judge the difference validity and proved it to be effective through practical experimentation.The method filled up the vacancy of difference theory.
