Dana Goward, President & Executive Director, Resilient Navigation & Timing FoundationThe U.S. Secretary of Defense has said “I hate GPS” and “I want to unplug the military from GPS.” Senior officials at the Department of Homeland Security (DHS) have called GPS “a single point of failure for critical infrastructure.”
GPS signals are used by virtually every technology. Their disruption for more than a brief period of time or over more than a small area could impact cell phone service, financial systems, computer networks, emergency radio systems, and every mode of transportation. It could be catastrophic for America.

Samuel Greaves, Space and Missile Systems Center commander and Air Force program executive officer for Space., U.S Air Force photo by Van Ha[Updated August 19, 2016, to include Air Force responses to Inside GNSS questions.] The U.S. Air Force has announced a new competition for the next GPS III satellite launch, scheduled for 2019. The request for proposal (RFP) for an Evolved Expendable Launch Vehicle (EELV) Launch Service, due from the industry by September 19, follows a draft RPF that received “extensive industry engagements,” the Air Force said.

A new report from the Government Accountability Office (GAO) outlines how, after decades of debate, the Department of Defense (DoD) system for buying and integrating space systems remains complex and fractured — causing delays, cost overruns, and cancellations among the department’s many space programs, including GPS.

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.

The GPS Directorate is requesting public comments on proposed changes to several interface specification (IS) and Interface Control documents (ICDs) for GPS signals in space. GPS receiver designers will be particularly interested in the changes as they affect how GPS signals should be processed in user equipment.

In February 2011, Russia launched the first satellite of the GLONASS-K1 series, i.e., SVN (space vehicle number) 801 (R26), which in addition to the legacy frequency division multiple access (FDMA) signals, for the first time was enabled to transmit code division multiple access (CDMA) signals on the GLONASS L3 frequency (1202.025 MHz). Later in 2014, the GLONASS program added SVNs 802 (R17) of series K1 and 755 (R21) of series M, and in 2016, SVN 751 of series M, with the capability of transmitting CDMA L3 signals to the constellation.

Graphic Depicting NDGPS Coverage After Site ReductionsThe 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.
