You may have seen the AMSAT CubeSat Simulator or CubeSatSim at Hamvention or at the AMSAT Space Symposium, or read about it in The AMSAT Journal or on social media with the hashtag #CubeSatSim.  This is a low-cost, fully assembled “lite” version of the CubeSatSim.  While it doesn’t have solar panels, batteries, or sensors, the AMSAT CubeSatSim Lite does have a working transmitter that sends simulated (generated by software) telemetry in five different modes including APRS, FSK, BPSK, SSTV, and CW.

The AMSAT CubeSatSim Lite comes fully assembled and ready to start transmitting as soon as you plug in the included power plug into an outlet.

There are two pushbuttons and two LEDs on the Lite board.  One pushbutton powers up the CubeSatSim Lite.  The other button is used to change the telemetry mode or shutdown the CubeSatSim Lite.  The green LED is the Power LED which indicates that the CubeSatSim software is running.  The blue Transmit LED indicates that the CubeSatSim Lite is transmitting.

If you connect your CubeSatSim Lite to your network (the included Raspberry Pi Zero W has WiFi) or your computer (using the included micro USB cable), you can log into it and customize it, and change modes and configurations.  For full information, see the README:

You can listen to the transmissions from the CubeSatSim Lite with any radio or scanner that receives in the amateur radio 70cm band at 434.9 MHz. To decode digital telemetry or pictures, you will need to use a SDR (Software Defined Radio) and software such as FoxTelem, an APRS decoder, or a SSTV decoder.  A good option is to use a Raspberry Pi single board computer with the Fox-in-a-Box Version 3 image, which can be downloaded for free here or on a Fox-in-a-Box Raspberry Pi SD Card.

Note that the CubeSatSim Lite board includes a 433 MHz chip dipole antenna (the black component on the left side in the photos) installed on the PCB so no external antenna is needed!  If you want to connect an external antenna, there is a place on the PCB for you to solder an SMA connector.

This item contains:

    • Raspberry Pi Zero W (green board on the bottom) is included!

    • AMSAT CubeSatSim Lite vB5 board (white board on the top) plugged into the Pi Zero W.

    • 16 GB micro SD card installed in the Pi with the open source CubeSatSim software which generates simulated telemetry data.

    • Four standoffs which secure the Lite board to the Pi.

  • Micro USB cable and power plug to power the Lite.

A case is not included.
