In terms of the lives of humans, the ionosphere makes it possible to bounce off radio wave signals that are used for communication and navigation. The ionosphere and troposphere both refract the GPS signals. Click on the ionosphere link. The lower region of the thermosphere (up to about 550 kilometers) is also known as the ionosphere. Where is the ionosphere located? The ionosphere is the part of the atmosphere where the ions exist and is important to HAM radio enthusiasts because they can use those ions to extend the reach of their radio communications. Normally, as any electronic signal, GNSS signals travel with the speed of light. The dominant forces of pressure gradient force and Coriolis force combine to form geostrophic wind flows. The ionosphere is a dynamic system controlled by many parameters including acoustic motions of the atmosphere, electromagnetic emissions, and variations in the geomagnetic field. The Ionosphere is part of Earth's upper atmosphere, between 80 and about 600 km where Extreme UltraViolet (EUV) and x-ray solar radiation ionizes the atoms and molecules thus creating a layer of electrons.
