SATLLA-0 (also known as satllazero) is an open source project dedicated to the development of a complete pico-satellite.
The overall vision is to enable both researchers and 12K to build a fully functional pico-satellite model based on a proven design that is fully functional in space (see SATLLA-2). The SATLLA-0 project includes both the software and hardware of the pico satellite (and ground station). The vision of the project is to enable any science class (in high school or university) to experience the "new space" at a fraction of the price of existing solutions.
The repo is structured as follows:
- software: The flight software is divided into three sub-folders:
- SAT0_Ground: The ground station module written in Arduino.
- SAT0_Master: The satellite main computer module written in Arduino.
- SAT0_OBC: The on-board computer (OBC) module written in Python.
- hardware: Contains the hardware schematics of the satellite.
- MD: Contains MD files describing the satellite commands, beacons and bill of materials (BOM).
- stl: Contains 3D sketches.
- paper: Contains the JOSS submission paper.
The SATLLA-0 core flight system is an open-source flight software used by the SATLLA-2B satellite. The library was designed as a starting point for academic institutions or schools that want to build or experiment with a laboratory or functional nanosatellite. As mentioned earlier, the system is divided into three parts. The main library contains the satellite's flight software, written in Arduino. Arduino is a C/C++ based programming language that is open source and easy to learn. The main library developed for the Teensy 3.x/4.x microcontroller family, which is the main microprocessor unit (MPU) of the SATLLA-2B nanosatellite. However, the library can be compiled for other microcontrollers using the definitions available in the library.
The SATLLA-0 flight software platform contains the following main features:
- A functional nanosatellites based on a Teansy microcontroller.
- An onboard computer to handle research activities based on RaspberryPi.
- A functional ground station based on ESP32 board.
SATLLA-0 is written in Arduino, and can be installed via Arduino, Teensyduino or any other IDE supporting Arduino.
A list of all the hardware required to assemble a functional nanosatellite is available here. The following boards are being used in this repository:
- SAT0_Ground: WiFi LoRa ESP32 from Heltec or TTGO.
- SAT0_Master: Teensy 3.6/4.1 microcontroller.
- SAT0_OBC: RPI-Zero or RPI-Zero-W.
