1. Indoor and outdoor integrated positioning work card, the work card supports outdoor GPS positioning with a positioning accuracy of 2 to 3 meters, and data support 4G or Lora transmission. The work card supports UWB positioning indoors, which requires the installation of our company's UWB positioning base station indoors. The indoor positioning accuracy can reach sub meters, and seamless switching between indoor and outdoor positioning modes can be achieved to manage personnel.
   
2. Applicable Scenarios

Our fusion positioning solution is ideally suited for scenarios encompassing large outdoor areas with simultaneous demands for precise indoor positioning. It enables pinpoint tracking of personnel and vehicles, achieving sub-meter accuracy both indoors and outdoors. Potential application domains include:

• Personnel positioning in chemical plants and oil depots
• Staff tracking in steel factories
• Worker monitoring in open-pit mines
• Personnel tracking at ports and terminals

2. Key Features

• High-Precision Positioning: RTK positioning accuracy reaches sub-meter level, complemented by UWB technology's similar precision.
• UWB Technology: Offers exceptional indoor positioning accuracy of up to 30cm, making it ideal for environments with weak or non-existent GNSS signals.
• RTK Support: Enhances outdoor positioning accuracy to sub-meter levels by correcting GNSS signals.
• Portability & Convenience: Lightweight and easy to carry, designed specifically for mobile use in dynamic settings.
• Multi-System Compatibility: Supports multiple satellite navigation systems (GNSS, GLONASS, BeiDou, etc.), ensuring global coverage.
• Weather Resistance: Crafted to withstand harsh weather conditions, suitable for outdoor use with an IP66 rating.
• Diverse Communication Modes: Offers flexibility with 4G/5G, WiFi, UWB, and LORA communication options.

3. Configuration Options

The HXZK-UBK fusion positioning card is available in various configurations tailored to specific needs:

5. RTK Positioning Architecture
5.1 4G Public Network Communication System Architecture
The system topology of the outdoor differential mode is shown below. The differential reference station data is transmitted to the server via 4G or RJ45 Ethernet port wired transmission. The positioning card obtains differential data from the server via 4G to complete high-precision position calculation and then sends the calculated high-precision position data back to the server via 4G.

5.2 LORA Local Area Network Transmission Architecture
As shown in the figure below, when 4G/5G public network communication is not convenient in certain scenarios, LORA can be used for data transmission. The communication distance between LORA and the integrated positioning card can reach 300 meters. Integrated positioning cards within a 500-meter radius centered on the LORA gateway can all perform data exchange through LORA. The differential reference station is connected via Ethernet cables and switches.

5.3 Indoor-Outdoor Integrated Positioning System Architecture

1. The indoor positioning work card communicates with the UWB base station without the need for cabling. After communication, the data is transmitted to the local server (cloud server) positioning platform via 4G/5G for position calculation.
2. In outdoor areas, the work card switches to Beidou satellite positioning, and the data is sent to the local server (cloud server) positioning platform via 4G/5G for position calculation.
