Description

technical field

[0001] The invention relates to the technical field of positioning, in particular to an indoor and outdoor integrated combined positioning device. Background technique

[0002] Positioning technology refers to the formation of a position positioning system through the integration of various technologies such as wireless communication, base station positioning, and inertial navigation positioning, so as to provide applications for military command, aerospace, transportation, meteorology, travel, emergency rescue, and safety monitoring Provides location services.

[0003] With the development of mobile communication and wireless sensor network, positioning technology has gradually entered a new stage. Satellite positioning and navigation technologies based on GPS and Beidou have been widely and maturely applied outdoors, but in indoor, underground, caves, urban streets, mountain jungles and other applications where satellite signals cannot be covered or are se...
