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 ...

Probing a planet’s ionosphere can be all about the timing. Confusion about how many layers of charged particles exist in the Martian atmosphere might be due to what time of day measurements were made.

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

The researchers modeled the ionosphere as a series of thin layers whose vertical structure follows established electron density profiles, allowing slant GNSS signals to intersect multiple ionospheric ...
