Satellite communication

The additional Doppler shift due to the satellite moving can be described as: f D, s a t = v r e l, s a t λ c {\displaystyle f_{\rm {D,sat}}={\frac {v_{\rm {rel,sat}}}{\lambda _{\rm {c}}}}} where v r e l, s a t {\displaystyle v_{\rm {rel,sat}}} is the relative speed of the satellite.
