Spatial Correlation of Transionospheric Signal-Time-Delays.

Abstract

Excess time delays of transionospheric radio signals introduce ranging errors in satellite-navigation and radar systems. The errors introduced by these delays can be compensated for by the prediction of the total electron content (TEC) along the signals' propagation paths. It is envisioned that such predictions should be updated at periodic time-intervals at specific locations. The question arises as to the extent of the geographic area surrounding a station with real-time TEC determination capabilities, within which TEC values could be interpolated within accepted accuracy.
