The IPS [[threaded code]] language, developed for AMSAT Phase III, is the first known use of a high-level language on board a spacecraft.<ref>Jan King "The Third Generation" [http://www.ka9q.net/AMSAT-ORBIT-3.pdf "Orbit" September 1980] p. 15</ref>

Another 16-bit IPS implementation was specifically developed to run on the ARM CPU in the IHU-2 on the AMSAT P3D.<ref>Chuck Green; Peter Gülzow; Lyle Johnson; Karl Meinzer; James Miller [https://www.amsat.org/articles/g3ruh/124.html "The Experimental IHU-2 Aboard P3D"] 1999</ref>

A 32-bit IPS implementation has been developed for the AMSAT P3E satellite and the AMSAT P5A mission to [[Mars]], which also have ARM CPUs. Emulators for both the classic 16-bit and the 32-bit IPS language and development environment are available for many other systems.<ref>[http://www.amsat-bda.org/IPS_Home.html "IPS Project Home Page"]</ref><ref>[http://www.retrotechnology.com/memship/amsat.html "COSMAC 1802 on AMSATs running IPS"]</ref><ref>[http://www.jrmiller.demon.co.uk/products/ipsbk.html "IPS - High Level Programming of Small Systems"]</ref><ref>[https://amsat-dl.org/en/ips-high-level-programming-of-small-systems-for-the-amsat-space-projects/ "IPS - High Level Programming of Small Systems for the AMSAT space projects"]</ref>
