Broadcast positioning system supporting location services through over-the-air television (tv) signals

A method, comprising:

• generating a plurality of communication frames, each comprising:
• a preamble configured to indicate a transmission time of a respective one of the plurality of communication frames;
• and
• a payload subframe comprising communications data;
• estimating a group delay between a time at which the preamble is generated and an estimated transmission time at which the respective one of the plurality of communication frames is to be transmitted;
• compensating an actual transmission time toward the estimated transmission time.

A non-transitory computer-readable medium, having stored thereon computer-executable instructions that, when executed, cause a processor device of a processor-based device to:

• generate a plurality of communication frames, each comprising:
• a preamble configured to indicate a transmission time of a respective one of the plurality of communication frames;
• and
• a payload subframe comprising communications data;
• estimate a group delay between a time at which the preamble is generated and an estimated transmission time at which the respective one of the plurality of communication frames is to be transmitted;
• compensate an actual transmission time toward the estimated transmission time.
