The Time Transfer Function as a tool to compute range, Doppler and astrometric observables

Hees, S.; Bertone, Stefano; Le Poncin-Lafitte, C.; Capitaine, N. (2013). The Time Transfer Function as a tool to compute range, Doppler and astrometric observables (Unpublished). In: Journées 2013 Systèmes de Référence Spatio-Temporels. Paris, France. 16-18 September 2013.

In this communication, we will show how the Time Transfer Function (TTF) can be used in the relativistic modeling of range, Doppler and astrometric observables. We will present a method to compute these observables up to second post-Minkowskian order directly from the space-time metric g_¥mu¥nu without explicitly solving the null geodesic. The resulting expressions involve integrals of some functions defined by the metric tensor taken along a straight line between the emitter and the receiver of the electromagnetic signal. Some examples are given within the context of future space missions.
