Abstract
A method of detecting a plasma depletion in the ionosphere includes comparing the large scale ionosphere trend with a local temporal slope of vertical or slant delay. In one example, the local temporal slope of delay is calculated phase data extracted from GPS signals at a GPS receiver, and the large scale trend is determined from broadcast ionosphere grid point delay data.
