Small Rocket – Image Transmission (LoRa 434 MHz)

This project demonstrates image transmission for a small experimental rocket, using an ESP32-CAM for image capture and Arduino MKR WAN 1300 for LoRa-based transmission and reception.
Instead of a live video stream, the system captures JPEG snapshots and sends them as 255-byte fragments over 434 MHz LoRa.

⚙️ Key Settings

Frequency : 434 MHz

Packet size : 255 bytes

Inter-packet delay : ~200–400 ms (tuned to reduce losses & respect duty-cycle)

Typical time per image : ~30–40 s

Reliability : ~80%

📸 Results

• Successful reception and reconstruction of JPEG snapshots
• Reliability ~80% after tuning delays and filtering duplicates

First successful received image

First successful captured image

👥 Team & Context

My teammate and I developed this project as part of the EIRSPACE association team.
It was carried out as a thematical project during our second year (Master 1 equivalent) at ENSEIRB-MATMECA (Bordeaux, France).
