Method and device for calibrating satellite positioning parameters, terminal device and storage medium

The embodiment of the invention provides a method and a device for calibrating satellite positioning parameters, a terminal device and a storage medium. The method comprises the following steps of: obtaining positioning data of a satellite positioning system to a terminal, determining position information of the positioning data at a position in a map database in the map database, and calibratingpositioning parameters of the satellite positioning system according to the positioning data and the position information. According to the method, the positioning parameters in the satellite positioning system are calibrated by adopting the real and accurate position information in the map database as feedback, so that the accuracy of the calibration of the satellite positioning parameters is improved. 本发明实施例提供一种卫星定位参数校准方法、装置、终端设备及存储介质。该方法包括：获取卫星定位系统对终端的定位数据，在地图数据库中，确定定位数据在地图数据库中的位置处的位置信息，根据定位数据和位置信息，对卫星定位系统的定位参数进行校准。本发明的方法，由于采用了真实准确的地图数据库中的位置信息作为反馈，对卫星定位系统中的定位参数进行校准，提高了卫星定位参数校准的准确性。
