Outlook for Civil GNSS Budget: Overcast with a Chance of Cuts

Though civilian GNSS activities fared reasonably well in the just-signed 2017 federal budget, the White House has already forecast cuts across non-defense agencies next year leaving the funding outlook for civil GNSS programs uncertain at best.

President Trump signed the fiscal year 2017 (FY17) spending bill on May 5, preventing another government shutdown and ensuring funding for agencies including the Department of Transportation (DoT), which is responsible for supporting civil GPS needs.

Florida Court Rules Against Law Enforcement Use of GPS Data Without a Warrant

In an opinion released earlier this spring, the Florida Fourth District Court of Appeal ruled against law enforcement use of data (including GPS-based data) from a car’s "event recorder" or "black box" without a warrant. The decision was just one of many in recent months that deals with the subject, as technology advances and privacy issues are clashing on a regular basis.

Door Open to New Bidders as Air Force Moves Closer to GPS III Buy

After a couple of changes in direction and spending some $18 million to verify the technical chops of their most likely suppliers, defense officials appear ready to buy up to 22 new GPS III spacecraft. Although three firms are now well positioned to bid on the potentially lucrative contract, the Defense Department continues to leave the contracting door ajar for newcomers, just in case.

2 SOPS Bids Farewell to GPS Satellite

At 25 years old, Global Positioning System Satellite Vehicle Number 27 completed its time in orbit on April 18, and the 2nd Space Operations Squadron (2 SOPS) said goodbye via final command after disposal operations were complete. SVN 27 was launched in 1992, meaning it lasted more than triple its design life of 7.5 years.

ABC Assessment Data Shows Wide Impacts to Some GPS Receivers

Test results from the long-running Adjacent Band Compatibility (ABC) Assessment show interference from wireless signals in nearby bands could negatively impact GPS receivers kilometers away from Long-Term Evolution (LTE) ground stations and render some more closely located GPS receivers useless.

A Raytheon executive said that the company expects to deliver the Block O Launch and Checkout System to the U.S. Air Force this fall as part of the GPS Next Generation Operational Control System (OCX).

In addition, the company completed a baseline procedure to recertify the troubled OCX program, which was approved by the U.S. Air Force, at the end of March, said Bill Sullivan, Raytheon vice president and program manager for GPS OCX, at the recent 33rd annual Space Symposium meeting in Colorado Springs, Colorado.
