The Meeting of the CGSIC is an annual meeting that takes place to ensure effective information exchange between civil GPS users and U.S. GPS authorities.

Subcommittees of the CGSIC for Timing, State and Local Government, International Information, and Survey, Mapping and Geosciences held their meetings on the first day of this year’s meeting. Summaries of these meetings were presented to the CGSIC Plenary Session by the Subcommittee Chairs the following day.

Each subcommittee focuses on a specific GPS user group and contained a variety of interesting applications. A presentation was given detailing impacts to the international telecom user industry from the GPS universal coordinated time (UTC) offset anomaly affecting the GPS ground control system in late January of this year. Briefings including GPS forensics and time synchronization in the electric power grid highlighted research and new uses of GPS that provide efficiencies and economic benefit the world.

The keynote speaker for this year’s CGSIC Plenary session was Brigadier General Mark Baird, vice commander of the Space and Missile Systems Center at Los Angeles Air Force Base. Baird spoke about the importance of positioning, navigation, and timing (PNT) as one of our nation’s most, if not the most, important mission to our national security. Noting integration of GPS in to every aspect of our everyday lives, he observed that the free, open, and reliable nature of this service has led to the development of hundreds of applications affecting numerous aspects of modern life. He also spoke of the proliferation of space technology, the increasingly contested, congested, and competitive nature of the space domain and budget constraints that are encouraging us to review our existing space architectures and identify what we need to change in order to improve resiliency, flexibility, and affordability.

Other presentations in the Plenary session focused on the operational status and modernization of the GPS constellation and ground control system, U.S. PNT policy, GPS augmentation systems, information related to U.S. engagement with other international Global Navigation Satellite Systems (GNSS) as well as a variety of topics related to the status and progress of ongoing GPS programs in the U.S. government.
