Broadcast Transmission of Information Indicative of a Pseudorange Correction

A method comprising:

• receiving, by an apparatus, global-positioning-system data from a plurality of global-positioning-system satellites;
• determining a measured satellite pseudorange for each global-positioning-system satellite of the plurality of global-positioning-system satellites based, at least in part, on the global-positioning-system data;
• receiving, by the apparatus, sensor data from at least one sensor mounted at a predetermined geographic location;
• determining an apparatus position of the apparatus based, at least in part, on the sensor data, the determination of the apparatus position being absent consideration of any global-positioning-system data;
• determining at least one pseudorange correction associated with at least one global-positioning-system satellite of the plurality of global-positioning-system satellites based, at least in part, on the measured satellite pseudorange and the apparatus position;
• and
• broadcasting transmission of information indicative of the pseudorange correction.

At least one computer-readable medium encoded with instructions that, when executed by a processor, perform:

• receiving global-positioning-system data from a plurality of global-positioning-system satellites;
• determining of a measured satellite pseudorange for each global-positioning-system satellite of the plurality of global-positioning-system satellites based, at least in part, on the global-positioning-system data;
• receiving data from at least one sensor mounted at a predetermined geographic location;
• determining an apparatus position of the apparatus based, at least in part, on the sensor data, the determination of the apparatus position being absent consideration of any global-positioning-system data;
• determining at least one pseudorange correction associated with at least one global-positioning-system satellite of the plurality of global-positioning-system satellites based, at least in part, on the measured satellite pseudorange and the apparatus position;
• and
• broadcasting transmission of information indicative of the pseudorange correction.
