of such term is equivalent to address time dilatio n [768]. Just as an example, let us consider

the SAGAS (Search for Anomalous Gravitation using Atomic Sensors ) mission propo sal,

which is intended, in essence, to fly highly sensitive atomic sensors (an optical clock and a

cold atom accelerometer) on a Solar System e scape trajectory [907]. Now, at the end of the

SAGAS mission, the a bove time-dilation term ...
