'''Technology for Autonomous Operational Survivability''' ('''TAOS''') (also known as '''TAOSSpace Test Experiment Platform 0''' and ('''STEP 0''') and '''USA101''') was a [[satellite]] developed by the [[United States Air Force|US Air Force's]] Phillips Laboratory (now part of the [[United States Air Force Research Laboratory|Air Force Research Laboratory]] Space Vehicles Directorate) to test technology for autonomous operation of spacecraft.<ref>{{cite web | url=http://www.globalsecurity.org/space/systems/taos.htm | title=Technology for Autonomous Operational Survivability | accessdate=2008-08-03 | publisher=GlobalSecurity.org}}</ref><ref>{{cite web | url=http://www.astronautix.com/s/step0taosp90-5.html | archive-url=https://web.archive.org/web/20170613131020/http://www.astronautix.com/s/step0taosp90-5.html | url-status=dead | archive-date=June 13, 2017 | title=Encyclopedia Astronautica: TAOS | accessdate=2011-08-27 | publisher=Encyclopedia Astronautica}}</ref>
