1. A method of using a Global Navigation Satellite System (GNSS), comprising forecasting transport of a region of plasma density enhancement within a polar region; the method comprising:
providing a convection model for predicting electrostatic potential distribution within the polar region over time;
determining total electron content distribution within the polar region;
determining whether reconnection is occurring;
based on determining that the reconnection is occurring:
identifying a region of plasma density enhancement using the total electron content distribution;
calculating a velocity of at least a portion of the plasma density enhancement using the convection model;
forecasting the region of plasma density enhancement over time;
predicting interruptions and/or disturbances to the GNSS signals based on the forecast; and
using the GNSS based on the prediction to thereby improve the reliability of outputs from the GNSS.
