Method and device for realizing positioning calculation, computer storage medium and terminal

Abstract

The invention discloses a method and device for realizing positioning calculation, a computer storage medium and a terminal, and the method comprises the steps: determining whether a tracking station used for carrying out real-time differential positioning (RTK) calculation on a first mobile station is included or not when the first mobile station uploads an observation value; when it is determined that the tracking station used for carrying out RTK solution on the first mobile station is not included, determining a second mobile station which obtains an RTK fixed solution and meets a preset condition as a temporary base station; selecting one of the determined temporary base stations as a tracking station for performing RTK calculation on the first mobile station; carrying out RTK calculation according to the selected tracking station which carries out RTK calculation on the first mobile station; wherein the second mobile station is another mobile station except the first mobile station. According to the embodiment of the invention, when the tracking station for performing the RTK calculation on the first mobile station is not included, the temporary base station is selected for performing the RTK calculation, and the coverage range of the RTK service is expanded under the condition of not increasing the tracking station.

Description

technical field [0001] This article involves but is not limited to satellite positioning technology, especially a method, device, computer storage medium and terminal for realizing positioning solution. Background technique [0002] At present, there are five widely used satellite navigation and positioning systems (GNSS) in the world, namely the US Global Positioning System (GPS), Russia's GLONASS (GLONASS), China's Beidou, the European Union's Galileo (Galileo), and Japan's The Quasi-Zenith Satellite System (QZSS). The satellite positioning system has high precision and covers the whole world. It has been widely used in many fields such as navigation, surveying and mapping, precision agriculture, intelligent robots, unmanned driving and unmanned aerial vehicles. The main factors that affect the accuracy of satellite positioning are satellite orbit and clock error errors, and atmospheric propagation errors. The errors of satellite orbits and clock errors calculated in rea...

Moreover, in areas where the ionosphere is active, such as low-latitude regions (the area between 30 degrees south latitude and 30 degrees north latitude), and the peak period of ionosphere activity that is a cycle every ten years (Bradford, 1996), even mobile stations The distance from the tracking station is more than 10 kilometers, and the RTK ambiguity is also difficult to fix

In this case, fast ambiguity fixation can only be achieved by increasing the density of tracking stations; this will undoubtedly increase the construction and maintenance costs of tracking stations
