Abstract: This paper discussed emphatically the extensive innovatory applications of GPS in military affairs，geophysics and geodesy，aviation aerospace， space technique， engineering-testing， traffic-transportation， industry and agriculture， summarized objectively in conclusion that GPS is a system-engineering with important strategic-significance and great useful-worth. It is third grand new applied-technology after the mobile communication and the internet. GPS will play ever more important function in national defence，national economy development and society of today field.
