Web1 jan. 2024 · However, they have a significant disadvantage associated with the influence of the ionosphere on the magnitude of the signal delay. This influence can be compensated for either with empirical ionospheric models or with maps or measured TEC values. In the first case, the standard is the Klobuchar model [ 1 ]. The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere.
