Description

technical field

[0001] The invention relates to a positioning device, in particular to a seamless positioning device for indoor and outdoor personnel using composite wireless network and sensing technology. Background technique

[0002] There are many kinds of indoor and outdoor positioning methods at present, such as GPS global positioning, inertial-based positioning, short-distance wireless communication-based positioning, and WIFI-based positioning. However, there are some problems in these positionings. For example, GPS global positioning is good for outdoor positioning, but its GPS signal is very weak indoors. Therefore, GPS global positioning cannot achieve accurate positioning indoors; the cumulative error based on inertial positioning is large, making The positioning effect is poor; positioning based on short-distance wireless communication can only be applied to short-distance wireless communication, and if the wireless communication distance exceeds the coverage ra...
