(MENAFN- EIN Presswire) EINPresswire/ -- Accurate estimation of the ionosphere is essential for reliable Global Navigation Satellite System (GNSS ) positioning, timing, and space weather applications.

Most operational systems still use a single-layer ionosphere model with a fixed effective height, despite the ionosphere’s strong spatial, temporal, and solar-driven variability. This simplification ...
