Ionosphere distance from earth
Web1 jul. 2024 · Modern “science” uses the ionosphere bounce theory to explain the long distance radio communication that otherwise would be impossible on a globular earth. And then, presto-chango, the formerly impenetrable ionosphere reflector suddenly allows the radio waves to pass right through when they need to explain radio communication to and … Web11 apr. 2024 · The Low Earth Orbit (LEO) satellites can be used to effectively speed up Precise Point Positioning (PPP) convergence. In this study, 180 LEO satellites with a global distribution are simulated to evaluate their contribution to the PPP convergence. LEO satellites can give more redundant observations and improve satellite geometric …
