DYNAMIC AUGMENTATION OF IONOSPHERIC CORRECTION DATA

A method, apparatus and computer program product are configured to dynamically augment ionospheric correction data. A method receives, from a requesting device, a request for grid layout data, where the grid layout data is associated with one or more geographical areas experiencing atmospheric delay incurred with a satellite-based positioning technique. The method transmits, in response to the request for the grid layout data, a grid layout definition message comprising a grid layout definition associated with the grid layout data associated with the one or more geographical areas. The method generates correction data based in part on the grid layout data, where the correction data is configured to correct the atmospheric delay incurred with the satellite-based positioning technique. The method also generates correction messages comprising at least a portion of the correction data and transmits the correction messages to the requesting device based on a dynamic correction data update rate.
