Problems solved by technology

[0005] The existing technology has made a lot of improved designs for vehicle navigation and positioning products, but most of them are limited to the improvement of product structure and function. Most of the navigation and positioning methods in the technology work independently and are not connected with each other in practical applications. In this way, the shortcomings of a certain navigation and positioning method will inevitably be exposed during the navigation and positioning process, affecting the actual navigation and positioning effect. Among them, especially in terms of satellite positioning, when encountering occlusion or changes in the atmosphere, it is easy to affect the positioning effect, but satellite positioning has its advantages and wide application range, so the existing single navigation method The shortcomings are gradually highlighted in practical applications

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a kind of vehicle positioning method designed by the present invention adopts inertial positioning device and satellite positioning device, and specific method comprises the following steps:

[0023] Step 001. Carry out preliminary positioning on the vehicle position through the satellite positioning device, obtain the current preliminary position of the vehicle, and enter step 002;

[0024] Step 002. Carry out calibration for the current preliminary position of the vehicle, obtain the current position of the vehicle, and proceed to step 003;

[0025] Step 003. Detect and obtain the satellite signal transmission strength of the satellite positioning device, and judge whether the satellite signal transmission strength is lower than the preset threshold, if yes, go to step 004, otherwise...
