I. Requirements Analysis:

With the continuous advancement of modern technology, the demand for precise measurement of personnel location and distance is growing. In various scenarios such as construction sites, emergency rescue operations, and military actions, rapidly and accurately obtaining horizontal and vertical distances between personnel, as well as their specific location information, is crucial for enhancing operational efficiency and ensuring personnel safety. Therefore, we have developed an integrated positioning and ranging device designed to address these challenges and meet the market's demand for high-precision, real-time positioning and ranging equipment.

II. Product Features:

1. High-precision distance measurement: The device achieves horizontal and vertical distance measurement accuracy of ≤1m, ensuring accurate distance information is obtained in all environments.

2. Real-time Measurement and Display: The device can measure and display distance data between individuals in real time, while providing voice announcements to help users quickly obtain measurement results.

3. Numerical Guidance and Directional Identification: The device employs numerical guidance to help users accurately identify personnel locations, thereby enhancing positioning efficiency.

4. Height Difference Measurement: When individuals are located on different floors, the device can accurately measure the height difference between them, providing users with comprehensive distance information.

5. BeiDou Positioning Function: The device integrates BeiDou positioning technology, enabling precise measurement of personnel's latitude and longitude information with an error margin ≤10m, meeting high-precision positioning requirements.

III. Application Scenarios:

1. Construction Sites: On construction sites, integrated positioning and distance measurement devices can be used to measure distances between workers, ensuring safe distances during construction processes. They can also be employed to measure height differences between floors, thereby enhancing construction efficiency.

2. Emergency Rescue: In emergency rescue scenarios such as fires and earthquakes, the device helps rescue personnel quickly locate trapped individuals, accurately measure distances, and enhance rescue efficiency.

3. Military Operations: During military operations, the device can be used for personnel positioning, distance measurement, and directional identification, enhancing combat effectiveness and personnel safety.
