Abstract:
    The positioning method by AGPS comprises: the GPS receiving terminal sends information on GPS satellite observation and local sub-zone to the AGPS positioning algorithm module; when the observation satellite number is two, the terminal device requests the satellite searching again; for every measurement, the algorithm module can obtain one curve crossed the sub-zone by combining satellite data and sub-zone labeled altitude information, and the receiving terminal is just on the curve convergence. This invention can overcome positioning defect in prior art.
