Abstract
A method, apparatus and computer program product are configured to adaptively adjust ionospheric delay correction grids and data transmitted to a navigation device based on identified ionospheric abnormalities.
Claims16
A computer-implemented method comprising:
- generating, by an ionospheric abnormality mitigation system related to a service provider, prediction data, wherein the prediction data comprises one or more ionospheric activity predictions, and wherein the prediction data is generated based at least in part on one or more ionospheric activity models associated with the ionospheric abnormality mitigation system;
- receiving observation data, wherein the observation data comprises data related to current ionospheric activity associated with a particular geographical area;
- comparing the prediction data and the observation data;
- determining, based in part on results of comparing the prediction data and the observation data, that an ionospheric abnormality is adversely affecting one or more navigational signals associated with the particular geographical area, wherein the particular geographical area is associated with two or more correction grids related to the atmospheric delay correction model, wherein the two or more correction grids at least partially overlap;
- generating ionospheric abnormality mitigation data;
- and
- updating at least one of the correction grids with ionospheric abnormality mitigation data, wherein updating at least one of the correction grids comprises executing one or more reconfiguration actions.

An apparatus comprised of processing circuitry and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processing circuitry, cause the apparatus at least to:
- generate, by an ionospheric abnormality mitigation system related to a service provider, prediction data, wherein the prediction data comprises one or more ionospheric activity predictions, and wherein the prediction data is generated based at least in part on one or more ionospheric activity models associated with the ionospheric abnormality mitigation system;
- receive observation data, wherein the observation data comprises data related to current ionospheric activity associated with a particular geographical area;
- compare the prediction data and the observation data;
- determine, based in part on results of comparing the prediction data and the observation data, that an ionospheric abnormality is adversely affecting one or more navigational signals associated with the particular geographical area, wherein the particular geographical area is associated with two or more correction grids related to the atmospheric delay correction model, wherein the two or more correction grids at least partially overlap;
- generate ionospheric abnormality mitigation data;
- and
- update at least one of the correction grids with ionospheric abnormality mitigation data, wherein updating at least one of the correction grids comprises executing one or more reconfiguration actions.
