Congress Likely to Delay Action on Budget Items, Affecting GPS

Congress is back in Washington with a December 9 deadline to pass the 2017 Fiscal Year (FY17) federal budget and avoid a government shutdown.

Lockheed Martin Awarded $395 Million GPS III Contract Option

Littleton, Colorado-based Lockheed Martin Space Systems has received a $395 million U.S. Air Force Space and Missile Systems Center contract option to build two additional GPS III satellites. The contract option calls for long-lead and production hardware to manufacture GPS III space vehicles (SVs) 9 and 10.

“The GPS III SV 9 and 10 satellites are expected to be ready for launch in 2022, thus sustaining the GPS constellation,” said Lt. Gen. Samuel Greaves, Space and Missile Systems Center’s commander.

Air Force Disposes of Long-Serving GPS IIA Satellite

Air Force Disposes of Long-Serving GPS IIA Satellite

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.

A funding shortfall will not halt work on the new GPS ground system this month, although a decision expected in the next two weeks may signal major changes in the program.

Increased personnel costs on the Global Positioning System Next Generation Operational Control System (OCX) program had eaten up the fiscal year 2016 budget and were poised to force managers to stop work on September 15. The Pentagon had requested Congress to allow $39 million to be reprogrammed to bridge the gap but lawmakers left for the summer recess without approving the change.
