As Navigation Uploads are/were performed over the following ~24 hours, GPS satellites will, one at a time, begin broadcasting this Future Leap Second, along with its date of effectivity and the Current Leap Second count, in accordance with IS-GPS-200. When specific satellites will begin broadcasting the new information will depend on the contact schedule over the next ~24 hours, which is dynamic and subject to real-time operations.

The planned reduction calls for the shutdown and decommissioning of 37 DGPS sites, leaving 46 operational sites available to users in coastal areas. The full notice can be found via this link: https://www.federalregister.gov/articles/2016/07/05/2016-15886/nationwide-differential-global-positioning-system-ndgps. Summary: 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. The service was implemented through agreements between multiple Federal agencies including the United States Coast Guard (USCG), Department of Transportation (DOT), and United States Army Corps of Engineers (USACE), as well as several states and scientific organizations, all cooperating to provide the combined national DGPS utility. However, a number of factors have contributed to declining use of NDGPS. Based on an assessment by the Department of Homeland Security (DHS), DOT, and USACE, the agencies will shut down and decommission 37 DGPS sites, which will leave 46 operational sites available to users in coastal areas. Termination of the NDGPS broadcast at the 37 sites is planned to occur on August 5, 2016.

Further investigation revealed an issue in the Global Positioning System ground software which only affected the time on legacy L-band signals. This change occurred when the oldest vehicle, SVN 23, was removed from the constellation. While the core navigation systems were working normally, the coordinated universal time timing signal was off by 13 microseconds which exceeded the design specifications. The issue was resolved at 6:10 a.m. MST, however global users may have experienced GPS timing issues for several hours. U.S. Strategic Command's Commercial Integration Cell, operating out of the Joint Space Operations Center, effectively served as the portal to determine the scope of commercial user impacts. Additionally, the Joint Space Operations Center at Vandenberg AFB has not received any reports of issues with GPS-aided munitions, and has determined that the timing error is not attributable to any type of outside interference such as jamming or spoofing. Operator procedures were modified to preclude a repeat of this issue until the ground system software is corrected, and the 50th Space Wing will conduct an Operational Review Board to review procedures and impacts on users. Commercial and Civil users who experienced impacts can contact the U.S. Coast Guard Navigation Center at (703) 313-5900.

The Air Force has produced 12 IIF satellites, featuring new clocks, new civil and military signals, and other upgrades for enhanced accuracy and robustness. Currently, there are 31 GPS satellites in operational service, including 11 Block IIF satellites and 20 spacecraft from previous generations. To learn more about the GPS constellation, go to www.GPS.gov . Date/Site/Launch Time: Wednesday, Feb. 03, 2016, from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. 18 minute launch window opens at 1347Z, 0847 EST. Rocket/Payload: A United Launch Alliance Atlas V 401 will launch the GPS IIF-12 mission for the U.S. Air Force. Launch Updates: To keep up to speed with updates to the launch countdown, dial the ULA launch hotline at 1-877-852-4321 or join the conversation at www.facebook.com/ulalaunch , twitter.com/ulalaunch and instagram.com/ulalaunch ; hashtags #GPSIIF12 and #AtlasV. Constellation Changes: The Air Force Second Space Operations Squadron (2SOPS) indicates that IIF-12, SVN-70/PRN-32, will replace SVN-41/PRN-14 in the F plane slot F1. SVN-23/PRN-32 (IIA-10) will be taken out of the operational constellation prior to SVN-70 launch and sent to Launch, Anomaly, Resolution, and Disposal Operations (LADO). PRN-04 is tentatively scheduled for assignment to the first of the new generation of GPS-III satellites, available for launch sometime in 2017. SVN-23, launched on 26 November 1990, has been an "Iron Bird" workhorse in the E-plane and has successfully served the world's GPS users for over 25 years. This is over 18 years past its designed service life, having operationally outlasted (and in many cases, outperformed) its peers on-orbit due to the diligent efforts of the men and women of the U.S. Air Force. SVN-41 will be re-phased from the F1 location to a newly defined F7 node (GLAN = 45°) once SVN-70 is set healthy.

GPS, operated by the dedicated men and women of the 2nd and 19th Space Operations Squadrons at Schriever Air Force Base, Colorado, is also the world's largest military satellite constellation. Uses of GPS include precise timing for financial transactions, search and rescue, communications, farming, recreation and both military and commercial aviation. The 2 and 19 SOPS, referred to as Team Black Jack, hosted GPS Week Feb. 15-20 to honor their heritage and interact directly with the Colorado Springs community. The week included a community geo-caching event, GPS/base tours for dozens of middle and high school students, 2 SOPS educational outreach events at local schools and culminated with a GPS heritage celebration. "We wanted to touch the different facets of our community and that's why we planned these events," said Tech. Sgt. Abifarin Scott, 2 SOPS GPS maintenance flight chief. GPS received historic recognition from the city of Colorado Springs a few months later. Colorado Springs City Council members presented a proclamation declaring July 17, 2015, GPS Day during a ceremony July 15. "It's a great time, a significant milestone that [GPS] has been active this long," said Andy Pico, Colorado Springs City Council member. "GPS has grown to be such a tremendous part of everybody's lives, it runs everything...it's so much into the fabric of everybody's life." The proclamation came as the Air Force celebrated GPS's 20 years of full operational capability, confirmed July 17, 1995. During the last 20 years, GPS has become an integral part of technology that affects the lives of billions of people around the world. The men and women of GPS stayed busy supporting many operations throughout the year. The Air Force and the 45th Space Wing supported the successful launch of a United Launch Alliance Delta IV rocket that roared to life March 25, carrying the Air Force's ninth Block IIF-09 navigation satellite for the GPS. 2 and 19 SOPS accepted satellite control authority of GPS IIF-9 Satellite Vehicle Number-71 April 3. 2 SOPS successfully completed a transfer operation of GPS satellite control authority to the Alternate Master Control Site at a backup location on June 6. 2 and 19 SOPS accepted command and control of the 10th GPS Block IIF satellite July 24. After 15 years of launch operations for the GPS, 19 SOPS completed their 26th launch as a squadron Oct. 31, performing checkout operations on the 11th GPS IIF satellite. On Nov. 6, Team Black Jack accepted SCA just six days after the Halloween launch of satellite vehicle number-73 - in record time. Members of Team Black Jack prepped for the launch and subsequent SCA acceptance of SVN-73 for approximately three months. The Command's GPS operations were showcased in multiple venues this year, engaging with communities and making the mission known all over the world. CBS featured the 50th Space Wing and GPS on an episode of 60 Minutes, and BLUE, the Air Force's flagship TV show, also featured GPS - both of which displayed the capabilities it offers to humanity. Beyond its essential capability for the military, GPS is a worldwide utility that provides the highest accuracy data available to people all around the world and enables such vital activities as weather forecasting, transportation, global commerce and farming/agriculture. "2 SOPS's continuing objective is to ensure GPS remains the gold standard for global space-based navigation and timing by providing highly reliable and accurate GPS signals to users around the world," said Lt. Col. Todd Benson, 2 SOPS Commander. "We look forward to continuing to provide our mission partners and global users with the most accurate position, navigation and timing signal available in the history of GPS."
