It has, for example, a large impact on the accuracy of positioning and navigation, but also on up-to-date GNSS applications such as autonomous driving and precision farming.

WebSky waves suffer most of their absorption losses in the ionosphere. As a radio wave passes into the ionosphere, some of its energy is absorbed by the free electrons and ions. If these free electrons and ions do not collide with gas molecules, most of that energy is converted back into electromagnetic energy, and the wave continues. http://kejian1.cmatc.cn/vod/comet/oceans/radio_waves/navmenu.php_tab_1_page_5_0_0_type_text.htm
