March 3, 2016 - Summary: The Department of Transportation, through the Office of the Assistant Secretary for Research and Technology (OST-R), will begin testing Global Positioning System/Global Navigation Satellite System (“GPS/GNSS”) receivers this April pursuant to the DOT Adjacent Band Compatibility Study (“the Study”) test plan published with this notice. Device testing will take place at the U.S. Army Research Laboratory at the White Sands Missile Range (WSMR) facility in New Mexico.
The Study provides for testing categories of receivers that include aviation (non-certified), cellular, general location/navigation, high precision, timing, networks, and space-based receivers. DOT seeks to include a broad range of devices used in rail, aviation, motor vehicle, maritime, and space transportation safety systems, among a number of other applications of GPS/GNSS. The goal of the Study is to evaluate the adjacent radiofrequency band power levels that can be tolerated by GPS/GNSS receivers, and advance the Department’s understanding of the extent to which such power levels impact devices used for transportation safety purposes, among other GPS/GNSS applications.

February 5, 2016 - LOS ANGELES AIR FORCE BASE - EL SEGUNDO, Calif. -- The U.S. Air Force and its mission partners successfully launched the 12th Boeing-built Global Positioning System GPS IIF satellite aboard a United Launch Alliance Atlas V Evolved Expendable Launch Vehicle from Space Launch Complex 41, Cape Canaveral Air Force Station, Fla. at 8:38 a.m. EST (5:38 a.m. PST)
"Today's launch is a significant achievement in the history of GPS, as we launch the last of the GPS IIF satellites to be delivered on-orbit," said Lt. Gen. Samuel Greaves, Space and Missile Systems Center commander and Air Force program executive officer for space. More

September 9, 2015 - The purpose of this Federal Register Notice is to seek comment from interested parties regarding a draft test plan that the U.S. Department of Transportation (DOT) has developed for the Global Positioning System (GPS) Adjacent Band Compatibility Assessment effort.
The objective of this test is to collect data to determine Interference Tolerance Masks (ITM) for categories of GPS and Global Navigation Satellite System (GNSS) receivers processing signals in the 1559-1610 MHz Radionavigation Satellite Service (RNSS) frequency band, as well as receivers that process Mobile Satellite Service (MSS) signals to receive differential corrections.

This Federal Register Notice seeks to inform the public of the requirements, the overall test plan, and the associated output data needed to successfully perform this component of the GPS Adjacent Band Compatibility assessment.

August 18, 2015, The Nationwide Differential Global Positioning System (NDGPS) service augments GPS by providing increased accuracy and integrity using land-based reference stations to transmit correction messages over radiobeacon frequencies.
However, a number of factors have contributed to declining use of NDGPS, resulting in a proposal to shutdown and decommission 62 DGPS sites, which will leave 22 operational sites available to users in coastal areas. A map of the proposed changes to NDGPS coverage can be found at http://www.navcen.uscg.gov/images/dgps/FRNDGPS.jpg
This Federal Register Notice seeks public comments on the shutdown and decommissioning of a total of 62 DGPS sites. Termination of the NDGPS broadcast at these sites is planned to occur on January 15, 2016.
DATES: Comments and related material must reach the Docket Management Facility on or before November 16, 2015

The Department of Transportation sought input on:
Choosing the Right GPS Navigation Device for Commercial Motor Vehicles
March 11, 2013, US DOT Federal Motor Carrier Safety Administration (FMCSA) in conjunction with U.S. Senator Charles E. Schumer (NY) announced an effort to publicize that not all GPS navigation devices are created equal and that some navigation systems are designed specifically for commercial truck and bus drivers.
Why does it matter which navigation system you use?
If you use a navigation system that does not provide you with important route restrictions, such as low bridge overpasses, the shortcut you thought would save you time and fuel, may, in fact, end up costing you a lot more money than you bargained for… More
