The vehicle satellite positioning management terminal can be used for vehicle positioning management, mining vehicle positioning, port and dock vehicle positioning. Through 4G data transmission, the positioning accuracy in centimeters and meters can be optionally selected. Through the management platform, real-time position display, trajectory playback, and electronic fence alarm functions can be achieved for vehicles.

1.Application Scenarios
The device can be used for vehicle positioning management in scenarios such as mining vehicles, port vehicles, tunnel construction vehicles, indoor forklifts, and vehicles in chemical industrial parks.

2.Device Features

• Supports satellite positioning with optional differential positioning, offering a standard positioning accuracy of 2-3 meters and differential positioning accuracy up to 3cm.
• Supports optional UWB positioning functionality, enabling indoor positioning or positioning in areas with severe satellite obstruction outdoors. Combined with our UWB base stations, positioning accuracy can reach sub-meter levels.
• Supports DC12-24V wide voltage power supply, allowing for power supply from the vehicle.
• Comes standard with a 3000mAh lithium battery, enabling continued positioning under vehicle power-off conditions.
• Optional tamper-resistant alarm function with disassembly alarm prompts.
• Supports TTS voice functionality.
• Adopts an integrated body design with an IP67 protection rating, supporting use in harsh outdoor environments.
• Supports 4G full-network connectivity with optional 5G/LORA/4G private network communication modes.
• Provides data interfaces supporting secondary development

3.Positioning Mode and Accuracy Selection

4.1 LORA Local Area Network Communication Mode Architecture
As shown in the diagram, the BQ positioning terminal transmits data to the LORA gateway via LORA wireless transmission, which then forwards the data to the server via 4G or wired (Ethernet) connection.

4.2 4G Communication Meter-Level Positioning Mode Architecture
The 4G public network transmission mode system architecture is illustrated below. The BQ positioning terminal transmits data to a specified IP address and port via 4G network, which supports nationwide networks and requires 4G signal coverage in the device's usage area.

4.3 Indoor-Outdoor Integrated Positioning Mode Architecture

1. The indoor positioning terminal communicates with the wireless UWB base stations to complete positioning, and the data is then transmitted via 4G/5G to the local (cloud) server positioning platform for location calculation.

2. In outdoor areas, the terminal switches to BeiDou satellite positioning, and the data is transmitted via 4G/5G to the local (cloud) server positioning platform for location calculation.

5.Application Cases

• Port Vehicle Positioning

• Mining Vehicle Positioning

• Historical Trajectory Playback
