AMSAT CubeSatSim First Official Release – v1.0

I am very pleased to announce the first software release of the CubeSatSim software v1.0!  Along with the first hardware release v1.0 last month, this is an important milestone for this AMSAT educational project.

All the CubeSatSim software and hardware is fully open source.  The v1.0 release info is available on GitHub and the v1.0 hardware info including Gerber files is available here.

Thanks to Bruce Paige, KK5DO, we have CubeSatSim blank PCB sets and CubeSatSim Raspberry Pi SD cards available on the AMSAT Store. For the moment, they are only available to ship to US addresses. In a post-COVID future, we hope to offer worldwide shipping.

The CubeSatSim Raspberry Pi SD Card  is a 16 GB micro SD card with Raspberry Pi OS Lite and all the CubeSatSim software installed and configured on it.  It is available at the AMSAT Store for $20.  You can also download the image and flash it to your own SD card using these instructions. Here is the readme file for the CubeSatSim software.

With the 3 board sets of blank PCBs, you can order the parts and solder your own CubeSatSim. They are available at the AMSAT Store for $35.

I want to take this opportunity to thank the team that has been working on the CubeSatSim Project including Pat Kilory, N8PK, Jim McLaughlin, KI6ZUM, and David White, WD6DRI.  In addition, Chris Thompson, G0KLA/AC2CZ has been instrumental in helping me get the FSK/BPSK transmit code working and has added support for the CubeSatSim to FoxTelem. Yesterday’s release of FoxTelem v1.11 has full CubeSatSim support.

And of course, thank you to the AMSAT Board of Directors and the AMSAT membership who have supported this project for many years.
