Method for automatic post-processing of GPS data in GPS System

摘要

PURPOSE: A method for post-processing GPS(Global Positioning System) information in a GPS system is provided to generate automatically the position information by using only the data of observational station. CONSTITUTION: GPS information is collected from a base station and a mobile station by driving an AI(Artificial Intelligence) engine and the collected information integrity is tested(401,402). A position of a virtual base station is calculated according to a result of the integrity test and a standby delay error of a radio wave is calculated(403,404,405). A clock error of a GPS satellite is calculated and a pseudo range between the GPS satellite and the mobile station is calculated(403,406,407,408). The generation of cycle slip is checked by using the GPS information and the clock error and the GPS information is verified(409,410). An uncertain integer is calculated and an opposite position of a carrier phase is calculated automatically(411,412) using the uncertain integer and entire wavenumber. The position information of a measuring position is calculated automatically(413,414).
