Problems solved by technology

Since the comprehensive influence of satellite orbit and clock error and atmospheric propagation error exceeds the meter level, although the orbit clock accuracy of each satellite navigation system is continuously improving, and more and more satellites are available, the standard unit without the support of external precision data The accuracy of SPP (Standard Point Positioning) has never been better than one meter
The above positioning accuracy cannot meet the requirements of surveying and mapping, precision agriculture, unmanned driving and other industries that require centimeter-level, decimeter-level, and sub-meter-level precision

Embodiment Construction

[0021] The embodiments of the present application will be described in detail below in conjunction with the drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0022] The steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer-executable instructions. And, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here.

[0023] In order to weaken the error that affects the satellite positioning accuracy, precise data can be used to improve the positioning accuracy. Among them, different positioning modes can be used according to different precision data, such as Satellite Based Augmentation Systems (SBAS), Differential Global Navigation Satellite System (DGNSS, Differential Global Navigation Satellite System), and Precision ...

Abstract

The invention discloses a cloud+ terminal positioning service method and system. The method comprises: a terminal sending observation data to the cloud server; the cloud server obtaining at least twokinds of position information through calculation according to the observation data and precision data collected by the cloud server, and selects optimal position information from the position information; the cloud server returning optimal position information to the terminal and calculates time information corresponding to observation data adopted by the optimal position information; and the terminal establishing virtual base station data according to the position information and the observation data, and performs real-time positioning by using the virtual base station data.

Description

Technical field [0001] This application relates to but is not limited to satellite positioning technology, especially a cloud + terminal positioning service method and system. Background technique [0002] At present, there are five widely used Global Navigation Satellite Systems (GNSS) in the world. They are the Global Positioning System (GPS) of the United States, the GLONASS of Russia, and the Global Navigation Satellite System of China. BeiDou satellite navigation system (BeiDou), EU's Galileo satellite positioning system (Galileo) and Japan's Quasi-Zenith Satellite System (QZSS, Quasi-Zenith Satellite System). A variety of satellite navigation systems can jointly provide users with positioning services, thereby greatly improving the availability, reliability and accuracy of satellite positioning technology. Satellite positioning technology has been widely used in many fields such as vehicle navigation, surveying and mapping, precision agriculture, intelligent robots, unmann...
