Problems solved by technology

However, these two methods still require external data to be supported, and these external data are also received through wired or wireless signal links. When the RTK real-time differential data is interrupted, these data links may also be interrupted, resulting in these The alternative doesn't work either

Abstract

The embodiment of the invention discloses a mobile station positioning method and device and a computer-readable storage medium. The method comprises a step of detecting whether the reception of real-time dynamic RTK differential data is interrupted or not, a step of taking a mobile station position calculated in a preset time range and a corresponding mobile station observation value as virtual base station observation values when the reception of real-time dynamic RTK differential data is interrupted, and performing RTK calculation according to the virtual base station observation values anda mobile station observation value at the current moment to obtain a mobile station position at the current moment. According to the embodiment of the invention, when the reception of the RTK differential data is interrupted, the mobile station position calculated in the preset time range and the corresponding mobile station observation value are taken as the virtual base station observation values when the reception of the dynamic RTK differential data is interrupted, centimeter-level precision positioning service can still be maintained under the condition that the reception of the RTK differential data is interrupted, and the support of other external data is not needed.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the technical field of satellite navigation and positioning, and in particular, relate to a mobile station positioning method and device, and a computer-readable storage medium. Background technique [0002] Global Navigation Satellite System (GNSS) is an artificial satellite system with multiple satellites. It can send signals containing position and time information to ground GNSS receivers. With the help of these signals, the receiver can achieve positioning. At present, the main GNSS systems include the European Union's Galileo satellite navigation system, the US Global Positioning System (Global Positioning System, GPS), the Russian GLONASS satellite navigation system and the Chinese Beidou navigation system. With the development of global satellite positioning technology, the demand for centimeter or even millimeter-level positioning accuracy is becoming more and more urgent, a...
