Beep-Sat is a complete software example for a simple beaconing satellite that performs a handful of tasks and runs forever.

Highlights

(top ⬆)

⭐ Software architecture that is easy to understand & build-upon

A simple asynchronous state machine schedules and runs routine spacecraft tasks

• Each task definition is contained within a single plain-text file
• Task files are easily added, removed, or modified

⭐ Well documented code with real-time debug messages

Entire code base includes thorough in-line commentary & insight

• During operation, descriptive messages are printed to the USB serial terminal
• Helpful coding patterns are discussed and software decisions are justified

Overview

As introduced in Hands-On Quick Start, whenever a PyCubed board is powered, it loads and runs main.py from the board's root directory.

• For this Beep-Sat example, all main.py does is automatically load each task file found within the /Tasks/ directory into a state machine and then runs the state machine indefinitely.
• Each task file defines its priority and frequency attributes to inform the state machine how often to run the task.
