The 59th meeting of the U.S. Civil GPS Service Interface Committee was held Sept. 16-17, 2019, in Miami, Florida. For readers who were unable to attend, Maritime Commons is providing the below synopsis of the meeting and presentations. The full agenda and presentations are available for download from the website.

The meeting of the CGSIC is an annual event, free and open to the public, conducted to provide official updates from U.S. GPS program officials and ensure effective information exchange between the U.S. government and civil GPS users. The two-day meeting is hosted by the Department of Transportation and the Coast Guard Navigation Center. DOT serves as the civil lead for the GPS and chairs the CGSIC in this capacity. NAVCEN is assigned duties as deputy chair and executive secretariat for the CGSIC.

Three subcommittees of the CGSIC (Timing, International Information, and Survey, Mapping, and Geosciences) held focused discussions on specific GPS topics such as NRL Time and Frequency Activities; Activities of the UN International Committee on Global Navigation Satellite Systems; and the Current Status and the Future of CORS Network.

The plenary session opened with a welcome from DOT’s Ms. Karen Van Dyke, CGSIC Chair, followed by a meeting overview given by NAVCEN Commanding Officer and CGSIC Deputy Chair Capt. Michael Glander. The keynote speaker was Diana Furchtgott-Roth, Deputy Assistant Secretary, DOT’s Office of the Assistant Secretary for Research and Technology. Furchtgott-Roth conveyed to the audience the importance of the U.S. Global Positioning System for transportation safety and numerous other civil applications and that its spectrum must be protected from harmful interference. She noted that, given threats from jamming and spoofing, the U.S. is committed to leading the world in PNT and to building and using the best possible solutions to maintain resiliency. In addition, Mr. James Platt, Director of Department of Homeland Security’s PNT Program Management Office, highlighted the need to understand cyber vulnerabilities in critical infrastructure supply-chain management. 

The plenary session included many other briefings related to the status of the U.S. GPS Program and the use of GPS around the world, including presentations from the National Space-Based PNT Coordination Office, U.S. Air Force, U.S. State Department, Federal Aviation Administration, Department of Commerce, and NASA.
