Low orbit height
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 … WebLEO satellites have a circular (or elliptical) orbit at a height of 250–2000 km from the Earth surface (Figure 14.3).The orbit period, mainly depending on the altitude, varies in the …
