Abstract

The invention provides a civil differential positioning technology based position determining method. The method comprises the steps that a base station receives detection data sent by a satellite, the data is transmitted to a data processing unit, the data processing unit acquires differential calibration information, and required data is sent to the base station; a vehicle-mounted terminal receives benchmark differential positioning information and satellite detection signals, acquires detection information and transmits the detection information to the base station; the base station calculates calibrated detection data by combining detection information acquired by a GPS antenna and the differential calibration information; and the data processing unit carries out coordinate transformation and filtering on latitude and longitude data in the detection information. According to the civil differential positioning technology based position determining method provided by the invention, precise positioning for vehicle information is provided, and a timely response can be provided when dealing with abnormal movements of a vehicle, so that the loss of property is avoided to the maximum degree.

Description

technical field [0001] The invention relates to GPS technology, in particular to a position determination method based on civil differential positioning technology. Background technique [0002] Automobiles have gradually become popular and become an important means of transportation for people to travel. However, as the number continues to increase, criminal activities such as traffic accidents and robbery are on the rise. Then the GPS positioning monitoring information system is widely used in it, and it plays an irreplaceable role. It can accurately record the vehicle status parameters, provide driving route monitoring and other services, and promote the safe and stable operation of the car. Most of the existing vehicle position monitoring systems are aimed at GPS positioning during dynamic driving, using a single satellite, which cannot meet the conditions of accurately detecting the state of the line and the positioning interference of buildings in the parking state, a...
