Air Force Backs GPS OCX as Temporary Shutdown Looms

The Air Force is defending the new GPS ground system, taking a stand against naysayers in Congress and declaring through its actions an intent to stick with the Next Generation Operational Control System program (OCX) — at least for now.

The most public of these actions occurred June 30 when Secretary of the Air Force Deborah Lee James announced OCX would surpass by at least 25 percent the program’s estimated cost. She declared a critical Nunn-McCurdy breach, putting the program on a path to automatic cancellation.

Pursued by GPS-Aided Advertisers? Check the Small Print

When we’re using a mobile location-based application such as getting driving directions from Google Maps, it’s not surprising to see advertisements from local businesses showing up in our browsers. Customized advertising, after all, is Google’s bread and butter.

But as owners of GNSS-enabled mobile devices move around through the world, they are often followed by similar unsolicited offers and advertising from apparently random sources.

What’s that all about?

The Emerging Legal Debate Around Japan’s QZSS

Japan’s regional and augmentation positioning system, the Quasi-Zenith Satellite System (QZSS), is a project yet to be developed. While it will become a constellation of seven satellites covering the western Pacific area, only “Michibiki,” the first satellite launched in 2010 for technological validation , is now in orbit.

Federal Agencies Plan Shutdown of 37 Differential GPS Stations

The U.S. Coast Guard, the U.S. Army Corps of Engineers (USACE), and the Department of Transportation (DoT) released a Federal Register notice today (July 5, 2016) announcing a reduction of the Nationwide Differential Global Positioning System (NDGPS).

The planned reduction calls for the shutdown and decommissioning of 37 DGPS sites, leaving 46 operational sites available to users in coastal areas. Termination of the NDGPS broadcasts is scheduled to occur on August 5, 2016.

Army Plans Awards, Solicitations for Assured PNT with(out) GPS

The U.S. Army will soon release new contracts and a post-Milestone B solicitation as part of its shift to a system of systems approach for making sure warfighters have the position, navigation, and timing (PNT) information they need regardless of issues with getting the GPS signal.

The Assured PNT (APNT) approach incorporates multiple sensors and an open architecture into an integrated whole that is resilient and easy to update, explained Kevin Coggins, the direct reporting program manager for PNT.

Homeland Security, PNT ExCom Move on Backing Up GPS

The Department of Homeland Security (DHS) is moving forward to establish a backup for the position, navigation, and timing (PNT) information provided by GPS. This month the agency assumed the lead in a yearlong effort to specifically define the requirements for an alternative source of timing information to and released a solicitation for research to help protect critical infrastructure from timing disruption or spoofing.

Senate Passes Defense Authorization Bill “Fencing Off” Funding for Next-Generation GPS Control System

The Senate approved defense authorization legislation last week before heading out for weekend campaigning. The measure contains a provision the White House said would further delay completion of the already overdue next-generation GPS control system (OCX) by 6 to 12 months.

Senators passed their version of the National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2017 on June 16, defying the White House, which had said June 7 it would veto the bill.

Iridium-based System, Proposed GPS Backup, Incorporates Crypto Protections

A new satellite-based positioning and timing system now available from partners Iridium and Satelles incorporates layered security elements into a service that offers 20- to 50-meter unaided position accuracy worldwide and could serve as a GNSS backup, according to the companies.

The Satelles Location and Timing (STL) service, also offers microsecond timing accuracy, said Satelles CEO Michael O’Connor — and that can be improved with more advanced receivers.
