Problems solved by technology
[0002] As a part of the Internet of Things, indoor and outdoor positioning technology plays an increasingly important role in life. GPS positioning technology has a good positioning effect outdoors, but indoors due to the influence of various obstructions, the GPS positioning effect is not good. Not very good, so indoor positioning is produced. Considering the influence of various factors such as positioning accuracy and positioning cost, an indoor positioning technology based on UWB came into being. UWB positioning technology can achieve centimeter-level positioning accuracy indoors
[0003] At present, most positioning systems can only achieve a single outdoor positioning or indoor positioning, and cannot combine the two
Although some positioning systems can realize the combination of the two, it is impossible to effectively switch between positioning systems, and repeated switching will cause waste of computation and poor user experience.
