Automatic positioning navigation system based on time correction

The invention discloses an automatic position and navigation system based on time correction. Compared with the existing system, a judge module, an information storage module and an information processing module are added in the system. The judge module receives a signal output by a GPS chip set and judges whether the signal output by the GPS chip set is normal, if the signal is normal, outputs directly the signal to an upper application module layer and stores the signal into the information storage module; and if the signal is abnormal, the judge module transfers the signal to the information processing module, the information processing module implements processing and predicting on ephemeris, almanac, clock correction parameter standard, clock correction and doppler shift, calculates position, speed and time of a receiver according to the signal, encodes the computing results, and outputs the encoded results to the upper application module layer. The system can well solve the navigation and position probl
