Experimental Satellite System 11 (XSS-11) One step closer to autonomous space rendezvous
| October 2005
XSS-11 is an experimental Air Force technology demonstrator designed to track other satellites. Controllers simply tell the spacecraft where to look for a piece of orbiting hardware—another U.S. satellite, for instance—and the XSS-11 autonomously plots a course, accelerates to the object, and begins to orbit and observe. It's the first step toward automatic satellite inspection and repair.
