What is the wireless video data transmission for mother and daughter UAVs?
Mother UAV is the main drone in the air, responsible for communicating with the ground and other daughter UAV drones in the air.
The daughter UAV is an auxiliary drone in the air, mainly responsible for executing the mission instructions issued by the ground control station through the main drone.
Wildfire surveying drone system description:
Lately, one of our customers asked for a feasible solution to set up a Drone network for wildfire surveying beyond the line of sight, by providing real-time data and video and operating over long distances. For the reason to cover large areas, since we are such a big country, we have proposed this architecture:
A mother UAV capable of flying up to 6 km in altitude and covering a distance of 50 کیلومتر, controlled directly via line-of-sight (LOS) from the ground control station (GCS). The mother UAV is equipped with a high-resolution inspection camera that transmits a high-quality video stream downlink to the GCS, and it exchanges command and telemetry data with the GCS through full-duplex, two-way communication.
علاوه بر, six daughter quadcopter drones connect exclusively to the mother UAV via two-way telemetry data and send their video streams to the mother UAV, which acts as a relay to transmit all data to the GCS. The daughter drones can operate simultaneously, and both the mother UAV and the daughter drones can be commanded from the GCS. The maximum distance between the mother UAV and the daughter quadcopters is set to 15 km LOS which makes it possible to cover a large area and establish beyond the line-of-sight system.

در اینجا نحوه استفاده موثر از آن آمده است:
1. پهپاد مادر به عنوان مرکز فرماندهی و کنترل
- ارتفاع بالا, نظارت دوربرد: پهپاد مادر, با قابلیت پرواز تا 6 کیلومتر در ارتفاع و پوشش 50 کیلومتر, می تواند به عنوان یک سکوی مشاهده در ارتفاع بالا برای منطقه آتش سوزی کلی عمل کند. می تواند تصاویر و ویدئوهایی با وضوح بالا ثبت کند, which can be streamed in real-time to the ground control station (GCS).
- مرکز هماهنگی پهپادهای دختر: پهپاد مادر می تواند به عنوان یک نقطه رله برای مدیریت پهپادهای دختر عمل کند, هماهنگ کردن مسیرهای پرواز خود برای پوشش بخش های خاصی از آتش سوزی.
2. پهپادهای دختر برای جمع آوری اطلاعات دقیق
- نظارت چند نقطه ای همزمان: The daughter drones can be deployed at lower altitudes to gather detailed video and telemetry data in different sections of the fire zone. With their high-quality cameras, they can provide focused views of active fire fronts, hot spots, or areas needing attention.
- Real-time mapping and telemetry: Data from the daughter drones can be relayed through the mother UAV to the GCS for real-time fire behavior mapping. This allows ground teams to make quick decisions about containment and evacuation.
3. Real-Time Data Processing at the Ground Control Station
- Mission planning and coordination: The GCS can receive telemetry and video streams from both the mother and daughter drones, allowing operators to adjust drone flight paths and focus on critical areas.
- Fire progression analysis: The high-resolution video streams from the drones can help assess how the fire is spreading, identify hotspots, and provide insights into where resources should be deployed.
- Integration with geographic information systems (GIS): The drones’ data can be overlaid onto maps to visualize fire expansion, terrain, and safe routes for ground personnel.
4. Benefits of the Drone Network for Wildfire Surveying
- Wide Area Coverage: With both the mother and daughter drones working together, you can cover a vast area in a short time, tracking the fire’s spread and monitoring multiple zones.
- Real-Time Intelligence: The system’s ability to provide live video and telemetry ensures that firefighters and emergency responders have up-to-the-minute information on the fire’s status.
- Safety and Efficiency: By using drones, you can reduce the risk to human lives by minimizing the need for manned aircraft or ground personnel in dangerous zones.
- Long-Distance Operation: The system’s range, with the mother UAV relaying data over large distances, allows the GCS to operate from a safe distance away from the fire while maintaining full control over the drones.
The detailed information about the communication links is shown in the following table:
