CubeSatSim
The CubeSat Simulator https://github.com/alanbjohnston/CubeSatSim/wiki is a low cost satellite emulator that run on solar panels and batteries, transmits UHF radio telemetry, has a 3D printed frame, and can be extended by additional sensors and modules. This project is sponsored by the not-for-profit Radio Amateur Satellite Corporation, AMSAT®.
Requires:
- wiringpi
- libcurl4-openssl-dev
- git
See the Wiki Software Install page for more details: https://github.com/alanbjohnston/CubeSatSim/wiki/Software-Install. To build and run the software on a Raspberry Pi 3B, 3B+, or Pi Zero W:
git clone http://github.com/alanbjohnston/CubeSatSim.git
cd CubeSatSim
Edit the afsk/main.c file to set your amateur radio callsign, then
make rebuild
To hear AFSK telemetry (X.25 data), your radio or SDR to 434.9 MHz FM, and you should receive telemetry from the CubeSat Sim:
./radioafsk
This code uses the Brandenburg Tech Digital Transceiver, based on DigitalTxRxRP https://brandenburgtech.wordpress.com/ If you don't have the SPI Interface enabled and the board plugged in, you will get an error.
This repository contains:
- afsk - Code that sends telemetry in 1k2 AFSK X.25 format
- arduino - Sample Arduino sketches to show how payload sensors can be interfaced to CubeSat Simulator
- ax5043 - Source for a library of functions to communicate with the AX5043 and configure the AX5043.
- cw - Code that sends telemetry in CW (Morse code) using AO-7 format
- libs - External libraries
- python - Python code for reading I2C sensors for current and temperature
- spreadsheet - Spreadsheets for decoding and analyzing the Simulator telemetry (see https://github.com/alanbjohnston/CubeSatSim/wiki/Decoding-Telemetry for details)
- wav - Wave audio files of CW or AFSK telemetry for listening or transmitting usng a CubeSat Simulator Lite
- demo.sh - a shell script to run the Simulator on boot using systemd (see https://github.com/alanbjohnston/CubeSatSim/wiki/Software-Install#autoboot-configuration for how to configure the Pi)
