We propose a broadcast positioning system (BPS) using ATSC 3.0 signal. Each TV tower will broadcast its own location and bootstrap signal emission time. ATSC 3.0 capable receivers will compute the pseudo-ranges based on the broadcast timestamp and the received time of the bootstrap signal. The pseudo-ranges will then be used to compute the location and time of the ATSC 3.0 receiver.

The paper will explain how the TV towers can be configured to accurately broadcast the time reference and how time and position can be computed at the receiver. TV signal coverage in the continental US will be analyzed for suitability of such a system. The paper will also show simulation results of position and time calculations based on tower geometry, time of arrival/transmission estimation errors, and multipath.

The location and timing information can be used to validate the integrity of GPS signal and as a fallback method when GPS is unavailable or compromised. The broadcast timing information can also be used to synchronize local clocks. The paper will describe some use cases and how broadcasters can help achieve the goal of resilient PNT
