I. Requirements Analysis:

During earthquakes and geological disasters, rapidly assessing the terrain of affected areas and conducting aerial search and rescue operations are critical components of relief efforts. As an efficient and flexible tool for search and rescue as well as surveying, drones can swiftly gather information in complex environments, providing robust support for ground search and rescue teams. Consequently, there is an urgent market demand for drones equipped with high-precision hovering capabilities, high flight altitudes, strong wind resistance, heavy payload capacity, remote control functionality, and high-definition video recording.

II. Product Features:

1. High-Precision Hovering: Equipped with an advanced flight control system, this drone achieves hovering accuracy of ±0.1m, ensuring stable suspension during search-and-rescue operations and surveying tasks to precisely capture target information.

2. High Flight Altitude: The drone can reach altitudes exceeding 5,000 meters, effortlessly handling flight missions in complex terrain and adverse weather conditions.

3. Strong Wind Resistance: With wind resistance rated at Level 6 or higher, it ensures stable flight in strong wind conditions to complete search and rescue and surveying missions.

4. High Payload Capacity: Flight payload capacity ≥ 2.7 kg, capable of carrying various search-and-rescue and surveying equipment to meet diverse mission requirements.

5. Remote Control: With a control range exceeding 8,000 meters, it enables remote operation and command, enhancing the efficiency of search and rescue operations and surveying tasks.

6. High-definition recording: Video resolution ≥ 960p, capable of capturing clear and detailed footage to provide robust support for rescue decision-making.

III. Application Scenarios:

1. Earthquake Search and Rescue: Following an earthquake, drones can rapidly take flight to conduct aerial search and rescue operations over the disaster area, locating trapped individuals while simultaneously capturing topographical imagery of the affected zone. This provides rescue teams with precise disaster zone intelligence.

2. Geological Disaster Surveying: During geological disasters such as landslides and debris flows, drones can be deployed to survey the terrain and topography of affected areas, assess the scale of the disaster, and provide data support for developing rescue plans.

3. Other Applications: This drone can also be deployed in forest fire prevention, environmental monitoring, and other fields, providing efficient aerial reconnaissance and monitoring services.
