Problems solved by technology
[0002] In the existing positioning scenarios, the user equipment uses Wi-Fi, Bluetooth (Bluetooth) and commercial frequency band wireless signals for positioning, but the user equipment needs to keep recording the collected data, resulting in a large memory consumption, and using wireless signals for positioning is harmful The consumption of air interface resources is also very large. In addition, in areas with poor wireless coverage, it will also affect the accuracy of positioning.

Embodiment Construction
[0077] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0078] Inertial navigation is a common relative positioning algorithm. In inertial navigation, given an initial position and an initial orientation, the position of the user device can be continuously tracked using the output of the inertial navigation sensor. The inertial navigation sensor includes a three-phase gyroscope, a three-phase accelerometer, and a three-phase magnetometer. The unit of the data output by the three-phase gyroscope in the coordinate axis centered on the user equipment is rad / s; the three-phase accelerometer is in The unit of data output on the coordinate axis centered on the user device is m / s^2; the unit of data output by the three-phase magnetometer on the coordinate axis centered on the user device is Tesla;...
