Problems solved by technology

[0003] At present, in order to solve the problem of excessive positioning error, more navigation and positioning satellites are launched
Launching more navigation and positioning satellites can certainly improve the accuracy of navigation and positioning, but the cost is high. In an environment where the reception of navigation and positioning satellite signals is relatively poor, the accuracy of navigation and positioning is still difficult to guarantee

Abstract

The invention discloses an implementation method of high-precision satellite positioning, which belongs to the field of navigation and positioning, and is mainly applied to occasions with high requirement on positioning precision. The implementation method comprises the steps of determining a direction, an angular speed and acceleration of a positioning carrier by means of a gyroscope, an accelerometer and a magnetometer, and finally outputting longitude and latitude as well as height information of the positioning carrier through calculation and correction, thereby providing more precise positioning.

Description

technical field [0001] The invention relates to satellite navigation and positioning technology. Background technique [0002] With the development of navigation and positioning technology, navigation and positioning are becoming more and more popular in daily life. However, due to the influence of weather and use environment, there are often different situations, and the positioning accuracy directly affects the navigation results. The device of the present invention supports the access of Beidou and GPS satellite positioning devices, establishes the direction, angular velocity and acceleration of the positioning carrier through gyroscopes, accelerometers and magnetometers, and finally outputs the longitude, latitude and height information of the positioning carrier after calculation and correction, and is tested by actual positioning The error is less than 1 meter. [0003] At present, in order to solve the problem of excessive positioning error, more navigation and posit...
