Heliocentric aberration for forward-backward distance measurement to a satellite
Abstract
The problem of the discrepancy between actual total path length for an electromagnetic pulse from a planet to a natural satellite as compared to instantaneous distance at reflection time is discussed. A correction for this effect is shown to be computable without making use of the heliocentric movement of the satellite and by iterating on the transit time. The correction is basically a function of the planetocentric elongation of the target body in respect of the sun i.e. the difference between the planetocentric longitudes of the satellite and the sun.
