Indoor precision positioning technology mainly includes Wi-Fi positioning, Bluetooth positioning, ultra-wideband positioning, geomagnetic positioning, etc. Through the principles of signal matching, triangulation, etc., it can achieve high-precision position determination in indoor environments, with an accuracy of centimeters to meters. It is often used in shopping mall navigation, warehousing management, medical care and other scenarios; outdoor precision positioning technology is mainly based on satellite positioning systems such as GPS and Beidou, combined with RTK base station positioning and other technologies, using satellite signal transmission time and distance for positioning. Generally, the accuracy is in the meter level or even higher, and it is widely used in traffic navigation, surveying and mapping, agriculture, logistics and transportation, etc., to provide accurate location information for people's travel, production activities, etc.
