The U.S. Air Force’s 2nd Space Operations Squadron (2SOPS) at the 50th Space Wing, Schriever Air Force Base, Colorado, has moved the longest-serving GPS satellite, space vehicle number (SVN) 23, into a disposal orbit several hundred miles above the operational GPS constellation.
The satellite, which was launched on November 26, 1990, had a rough start, the Air Force said. After early-orbit operations and initial stabilization in December 1990, SVN 23’s solar array stopped working.
