Abstract
We studied relativistic effects on spacecraft clock rates for ESA’s JUICE mission and derived a relationship between dynamical time TDB and on‐board time. We analysed the S/C on‐board clock rate by using the JUICE mission nominal trajectory. We identify significant changes in the rate of the clock due to large changes of the S/C velocity and its distance to the solar system bodies during the various spacecraft operational phases. After ≈ 11.5 years, at the end of the mission, the offset in time between dynamical time TDB and the on‐board clock may run up to ≈ 3.22 seconds due to relativistic effects.
