Ionosphere function
WebThe ionosphere is the region of the upper atmosphere characterized by a large population of free electrons and ions—the atmospheric shrapnel that arises when UV photons from the Sun knock electrons from atmospheric gas. (For a tour of the upper atmosphere, see the Quick Study by John Emmert, Physics Today, December 2008, page 70 .) Web1 dag geleden · Thirty days of operation are considered. The corresponding accuracy cumulative distribution function is also reported. Table 3 also shows the 90th and 50th percentiles of the cumulative functions for the 3D and horizontal position accuracy, computed on three different positions of interest on the Moon (South Pole, Daedalus …
