The emphasis is on the two-way Doppler, which is of particular interest for range and range rate measurements. It is shown that the classical and relativistic two-way Doppler equations are identical. All derivations are based on time, propagation delay and phase rather than on frequency because the electronic equipment is only capable of measuring finite differences in time and phase. This approach also unifies the treatment of both classical and relativistic Doppler and the integration of Doppler frequency.
It is also shown, that range and range rate measurements are not independent measurements and that range rate measurements can be performed much more accurately than range measurements. The contributions of range measurements to orbit determination are therefore rather limited except for near earth phases of a mission.Numéro de notice : 15966 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Monographie Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82240 Exemplaires(1)
