Welcome to the AMSAT® CubeSatSim Project Wiki, the CubeSat Simulator

The CubeSatSim is a low cost satellite emulator that runs 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®.

Here you will find documentation about this project and detailed install instructions.

This is the vB5 version of the CubeSatSim. If you have an older version of the CubeSat Simulator, you might be looking for these instructions.

The instructions for the latest version is here.

The CubeSatSim has the following features:

• Working solar panels and rechargeable batteries

• Multi-channel voltage, current, and temperature telemetry transmitted in the Amateur Radio UHF band

• Telemetry decoding using FoxTelem software or APRS software

• STEM Payload board with STM32F103C8T6 “Blue Pill” Arduino compatible & sensors

• Tape measure monopole or SMA antenna

• Integrated Band Pass Filter

• New 3D printed frame and solar panels

If you don't have the time or money to build a CubeSatSim that transmits real telemetry, you can build a CubeSat Simulator Lite

Here are the four boards that make up the complete board stack. Left to right: Raspberry Pi Zero WH, Main Board, Battery Board, and STEM Payload Board.

Here is the built board stack:

There is a 3D printed frame, including solar panels:
