1. A system for providing location correction data to receiving devices, the system comprising:
multiple base stations, wherein a first base station of the base stations is configured to:
generate a first corrections stream including (a) a first error data for one or more satellites that contributes to an error in determining a location of receiving devices, and (b) a first location data of the first base station, and
transmit the first corrections stream;
a processing server, wherein the processing server is configured to:
receive multiple corrections streams from the base stations,
generate a composite corrections stream from the corrections streams, wherein the corrections streams are indexed based on location data of the base stations, and
transmit the composite corrections stream to multiple television stations for broadcasting in a television broadcast frequency; and
a receiving device, wherein the receiving device is configured to:
receive satellite location data from the one or more satellites to compute a location of the receiving device,
receive the composite corrections stream broadcasted from a television station of the television stations,
select a specified corrections stream corresponding to a specified base station from the composite corrections stream, and
correct the location of the receiving device based on a specified error data from the specified corrections stream to generate a corrected location.
