Ionospheric signature on Doppler shift during a Martian year. Data extracted for different Ls, for a 20° elevation with respect to the asset at 06:00 SLT. The dashed red and dotted bleu lines correspond to an asset in the Northern and Southern hemispheres respectively. The ionospheric signature on Doppler shift is given for UHF (0.4 GHz, bottom), S-band (2 GHz, middle) and X-band (8 GHz, top) radio signals.
