The Gaia-RVS is a integral-field spectrograph with no calibration device onboard. The instrument will be self-calibrated through the reduction procedure; but it needs a list of well-know stars to define the zero-point and to initiate the iterative reduction process. The IAU RV-standards are not numerous enough (some 140 objects; whereas some 1500 are needed), and many are too bright for the RVS. A new list has been defined, with criteria adapted to the RVS capabilities: magnitude and spectral range, no double stars, no variables, "clean" environment up to 80 arcsec, uniform sky coverage. The stars were taken from a few existing good lists, and each one needs to be reobserved at least 2 times before launch (2012), and also during the mission (end 2018). The list is now ready, and the reobservations are going on at high rate. This list should be released in a near future, so that everyone can use it, and eventually improve it.
