The device supports GPS high-precision positioning, with a positioning accuracy of up to 3 centimeters in RTK mode. It also supports UWB positioning, and indoor installation of UWB positioning base stations can achieve sub meter accuracy in indoor positioning. The device can be used for mine personnel positioning, steel plant personnel positioning, open-pit mine personnel positioning, oil depot personnel positioning, and other scenarios. The data is transmitted to the server management platform software through 4G to achieve real-time display of personnel positions, historical trajectory queries, electronic fences in hazardous areas, and other functions.

The wearing method of the portable positioning terminal is shown in the following figure.

Portable RTK terminals are mainly used to provide high-precision position data, supporting indoor UWB positioning and outdoor satellite positioning functions. The integration of ultra wideband (UWB) and real-time kinematic (RTK) technologies in portable positioning terminals represents a significant advancement in accurate position tracking. This UWB+RTK portable positioning terminal is designed to provide high-precision, real-time location data in various environments, meeting the needs of industries that require precision and mobility.

1. Architecture of 4G Public Network Communication System
The topology diagram of the outdoor differential mode system is shown below. The differential reference station data is transmitted to the server through 4G or RJ45 network port wired transmission. The positioning terminal obtains differential data from the server through 4G to complete high-precision position calculation, and then sends the calculated high-precision position data to the server through 4G.
