New GPS Ground Control System Likely to Continue with Modifications

Air Force Space Commander Gen. John Hyten

The Department of Defense (DoD) is less than three weeks away from a decision on whether to retain, cancel, or change its contract to develop a new GPS ground system.

A source familiar with the program said they believe the Air Force will stick with the program but will recast it to fit more closely with DoD’s budget realities.

Spirent Announces Interference Detection and Analysis Unit

Spirent Communications plc’s Positioning Technology Unit has announced the GSS200D Interference Detection and Analysis solution, developed as part of Spirent’s partnership with Nottingham Scientific Limited.

The GSS200D comprises field-based hardware and a secure data server for automatic capture and analysis of GNSS radio frequency interference. According to the Paignton, UK–based company, deployments of GSS200D probes provide users with a thorough understanding of the RF interference (RFI) environment at sites of interest.

Lockheed Martin Awarded $395 Million GPS III Contract Option

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.

Low-cost, precision, GNSS receivers will become a reality in the driverless cars, drones, and smartphone markets by 2021, said ABI Research in two new reports, “Precision GNSS in Automotive” and “GNSS IC Design Trends: Modules, Standalone, Combo, and Embedded.”

The automotive industry will be the main driver behind precision GNSS receiver adoption, in which centimeter-level accuracy is essential to complete driver safety systems with the redundancy necessary for autonomous vehicles, the company said.

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.

GPS Directorate’s Whitney: No Immediate GPS OCX Work Stoppage

Col. Steve Whitney, GPS Directorate

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.

DHS Continues to Test GNSS Timing for Critical Infrastructure

Because GPS and other GNSS are critical to the nation’s infrastructure, the U.S. Department of Homeland Security (DHS) is testing an augmentation system and developing new requirements to protect it, a DHS official told the U.S. Department of Transportations’s Civil GPS Service Interface Committee (CGSIC) meeting this week in Portland, Oregon.
