The local geometric model considered corresponds to local Fermi coordinates associated to an observer O and Fermi transported tetrads, and by using Synge’s world-function the measurement formulation for the relative distance in terms of the O-proper time s1, corresponding to the instant at which an electromagnetic signal is emitted from O, and the O-proper time s2 at which the signal is received by O after a trip-time to complete a circuit is presented.book parthttps//doi.org/10.1007/978-3-642-10634-7_8http://link.springer.com/chapter/10.1007%2F978-3-642-10634-7_8?LI=true#metadata only access52531.51GravimetryGeneral relativityFermi coordinatesAstronomía (Física)
