The ATSC 3.0 protocol offers a unique capability to broadcast precision Position, Navigation, and Timing signals nationwide. This capability could be used as a national GPS augmentation and replacement in the event of a GPS wide area outage. The PNT Advisory Board is charged with recommending to the Government technologies and methods to provide the critical infrastructure support services in the event of GPS loss of service. The national deployment of NAB member transmission systems and the ability to “network” precision time distribution is very important and compelling. Techniques exist to implement a time distribution of a common time base, UTC, within the ATSC 3.0 protocol. The author will work with NAB to identify and design exactly how this could be done.
