Read before installing. Link only: a system image still offered by the project (2.5G in the directory listing, file dated 2025-07-02). Official file: https://cubesatsim.org/download/cubesatsim-v2.1.iso.zip. Writing: the project wiki (https://github.com/alanbjohnston/CubeSatSim/wiki/2.-Software-Install) uses balenaEtcher and a 16 GB or larger microSD card; Raspberry Pi Imager cannot apply its OS customisation (user, Wi-Fi) to a custom image. First boot: the software starts on power-up; log in as pi / raspberry (hostname cubesatsim) and change the password, set the callsign with CubeSatSim/config -c (default ID is AMSAT) and the APRS position with CubeSatSim/config -l; Wi-Fi is set with sudo raspi-config. No checksum is published. The software is GPL-3.0 (alanbjohnston/CubeSatSim); the image is a free download from AMSAT's open download directory https://cubesatsim.org/download/.
