Broadcast Positioning System (BPS) as a Complementary Time Source to GPS for Datacenters. 

(Possibly make it a joint submission with Safran, Equinox and Nexstar).

Datacenters and users of IT systems require precision timing for systems and services. The industry agrees that complementary GPS delivery sources are a need for critical infrastructure. Broadcast Positioning System (BPS) is proving to be a useful service for accurate, efficient, alternative time transfer.

This presentation will discuss an example of how a BPS implemented ATSC 3.0 television station can be used to transfer precision time to a major datacenter in a large city. We will describe a practical approach for using BPS as a complementary time transfer service that does not rely on GNSS. The system accuracy of the BPS time transfer will be discussed as well as the practical system architecture. This is part of a nationwide effort to build a BPS system as part of the ATSC 3.0 standard.
