(a) Schematic representation of the observation of the spacecraft by two spaced stations during a radio-sounding experiment. (b) The algorithms of local correlation. sA(t) and sB(t) are the received signals at the two different stations. The local correlation compensates for the Doppler shift of spacecraft using the spacecraft’s priori ephemerides.
