FalconResQ – Short Project Report

1. Overview

FalconResQ is a drone-assisted search & rescue system using LoRa (866 MHz) communication. It detects distress beacons and relays their packets to a ground station in real time. Built using Heltec WiFi LoRa 32 V3 (ESP32-S3 + SX1262), it ensures long-range, low-power, robust communication.

2. System Components

2.1 Distress Beacon

• Periodically transmits packets at 866.1 MHz
• Includes Beacon ID, battery, optional GPS

2.2 Drone Receiver

• Listens on 866.1 MHz continuously
• On receiving a packet → switches to 866.9 MHz → relays to ground station
• OLED shows RSSI & packet data

2.3 Ground Station

• Receives forwarded packets on 866.9 MHz
• Displays & logs data for mapping

3. Key Features

• Long-range LoRa communication (0.5–8 km depending on altitude)
• Multi-channel frequency planning
• Real-time packet relay
• Simple architecture with minimal latency

Example: FALCON01,52,78,12.93,77.59

6. Test Results

• RSSI values during testing: -65 to -92 dBm
• Strong & stable reception outdoors
• Verified instant switching between RX and TX

7. Future Enhancements

• Multi-channel beacon scanning
• Drone GPS integration
• Mobile dashboard for live mapping
• Multi-drone mesh network for range extension

8. Conclusion

FalconResQ is a lightweight, efficient, and scalable S&R communication system. It enables drones to detect distress signals and relay them over long distances, making it suitable for real-world deployment in disaster zones.
