Description

technical field [0001] The invention relates to a Beidou navigation self-optimization device and a self-optimization method thereof capable of improving the continuity of Beidou-based navigation and positioning terminal signal detection and navigation accuracy, and belongs to the field of navigation technology. Background technique [0002] The main principle of satellite positioning technology is to place a GPS receiver at an undetermined position on the ground, and receive signals transmitted by more than 4 GPS satellites at the same time. The positions of the four or more satellites at this moment and their respective distances to the receiver are determined by a certain method, and the position of the test point and the clock error of the receiver are calculated by using the distance intersection method. [0003] The Beidou Navigation Satellite System (BeiDou Navigation Satellite System) is an independently developed and independently operated global satellite navigation...

AI Technical Summary

Problems solved by technology

[0004] The existing Beidou positioning platform is mainly used for information service management and command and dispatch center to realize remote positioning monitoring and management of Beidou vehicle-mounted or ship-borne navigation and positioning terminals and Beidou navigation mobile terminals. It has not yet been completed, and it cannot achieve full coverage and high-precision navigation and positioning. Because the construction of the ground segment of the Beidou navigation system is still in progress, the various navigation and positioning information transmitted and adjusted by the ground station has yet to be improved. Now the coverage of the Beidou navigation system Not wide enough, usability is not high enough, continuity is poor, navigation and positioning accuracy is not enough

When the existing Beidou navigation and positioning terminal and Beidou positioning platform provide positioning and navigation services and remote positioning monitoring and management, Beidou signal strength detection and feedback cannot be performed. For areas where the Beidou signal is weak or the Beidou signal is shielded, the existing Beidou navigation The positioning terminal is also unable to perform effective self-optimization, so that the current Beidou navigation and positioning terminal does not provide users with a good enough navigation experience, and the existing Beidou positioning platform cannot count and detect the Beidou signal strength of the Beidou positioning and navigation terminal. Unable to provide powerful data collection for the trial operation of the Beidou navigation system
