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

July 15, 2015 - LOS ANGELES AIR FORCE BASE, Calif. -- The U.S. Air Force and its mission partners successfully launched the 10th Boeing-built Global Positioning System IIF satellite aboard a United Launch Alliance Atlas V launch vehicle from Space Launch Complex 41, Cape Canaveral AFS, Fla. at 11:36 a.m. EDT.
"Today's successful launch is a testament to the outstanding team work of government and industry partners' commitment to mission success. The GPS IIF satellites are critical for GPS constellation global service for years to come," said Lt. Gen. Samuel Greaves, Space and Missile Systems Center commander. More.
March 23, 2015, The purpose of this notice was to seek comment from the public and industry regarding potential plans by the United States Government to implement an enhanced Long Range Navigation (eLoran) system as a complementary positioning, navigation, and timing (PNT) capability to the Global Positioning System (GPS).

March 12, 2015, The U.S. Department of Transportation hosted a workshop to continue discussions on the Global Positioning System (GPS) Adjacent Band Compatibility Assessment
The workshop focused on the following topics: (i) identification of GPS and Global Navigation Satellite System (GNSS) receivers to be considered for testing that are representative of the current categories of user applications; and (ii) discussion of a GPS/GNSS receiver test plan… More.
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
