WebThe mapping function is crucial for the conversion of slant total electron content (TEC) to vertical TEC for low Earth orbit (LEO) satellite-based observations. Instead of collapsing the ionosphere into one single shell in commonly used mapping models, we defined a new mapping function assuming the vertical ionospheric distribution as an exponential profiler … Web7 mei 2024 · This paper describes a novel sounding system for which the functions of the medium frequency (MF) radar and the ionosonde are integrated on the same hardware … WebJapan's first Ionosphere sounding satellite was named Ume. It was used to monitor radio waves in the ionosphere and forecast conditions for optimal use of shortwave communications.
