"Web4 aug. 2024 · The ionosphere begins about 35 miles up, some 18 miles above where the ozone layer leaves off. It is chiefly notable for its ability to reflect radio transmissions, enabling them to follow the curvature of the Earth though in other circumstances they would travel in a straight line. The layer which does this is called the Heaviside layer. " - Ionosphere and troposphere delays

WebThe ionosphere and troposphere are the two main layers of the Atmosphere that cause delays in GNSS observations. A linear combination of the dual-frequency data can be used to reduce ionospheric delay. Unlike the ionospheric delay, the tropospheric delay cannot be eliminated using the same methods.

Webof satellite ephemerides, effects of ionosphere and troposphere are almost eliminated by forming DD (double-difference) measurement equations. With a medium length baseline under 100 km, in particular ionosphere effects are hard to be canceled by DD. In this case, dual-frequency measurements are often used to eliminate the ionosphere effects.
