It is shown that using existing ground based photometric data it is feasible to produce a set of secondary standard stars for HIPPARCOS photometric calibrations, with a density over the sky sufficient for monitoring the short and long-term variations of the main mission detection chain. The final accuracy on Hp is slightly lower than required for red stars, i.e., 0.03 instead of 0.02, whereas that on (B-V) is better with se = 0.01 mag. The faint standards problem can be solved by ground based observations prior to satellite launch. The Tycho calibration should not present any difficulty regarding standard availability as the expected number of standards is more than double when the conditions on pressure and Input Catalog inclusion are relaxed.
