Samuel's Atmospheric Live Telemetry (SALT) is a rocket made by @samuel300p which features transmitting live telemetry from the rocket to a ground station using LoRa.
The main sensors and components include:
- A Raspberry Pi Zero 2 W
- 2 LoRa modules (EBytes' E22-400TXX series) transmitting @ 433.125MHz
- BMP280 for pressure and temperature
- BNO055 for orientation, acceleration, and magnetometer data
- An OV5647 camera for recording footage
There are 2 programs in this repository, the flight software and the ground station software.
The flight software, when first started, will wait for the command from the ground station to start transmitting telemetry in real time and logging all sensor data at 50Hz, and start recording footage from the camera.
The ground station software will receive the telemetry data and display it in real time.
This is written in Rust (experimental, since I'm still learning Rust). To get started, you
simply need to build the project with cargo build --release and run cargo run --release.
Note: If you want to skip waiting for compilation on the Pi Zero 2W, you can cross compile via cross and Docker - cargo install cross,
and then: cross build --target aarch64-unknown-linux-gnu, and then copy the binary (from target/) to the Pi Zero 2W.
A prototyping script in Python is available as main.py for testing purposes, but it is not used in the final flight software.
Similarly, there's also a testing script written in Rust in src/bin/test.rs. Run it with cargo run --bin test.
This is 100% vibe coded (the code looks really awful, but it works). There is a rocket visualization and telemetry data display with graphs. The GUI backend is written in Python using PyQt6. It also logs all the telemetry data to a CSV file for later analysis (TODO!).
To run the ground station software, using uv:
