N2 - We present the general architecture of the GI2T/REGAIN control system.
Based on a Graphical User Interface and different client-server
communications, the system has to control both telescopes, the delay
line, the beam-combiner, the data acquisition system and the real-time
processing used as fringe tracker. We also describe in details the
implementation of a real-time fringe tracker based on 4 monochromatic
images and which used the fractional excess algorithm. Numerical
simulations are shown. The control system is also dedicated to the
acquisition of all the relevant data for the visibility calibration. We
will also describe in details the data reduction package that provides
the corrected visibilities. This architecture is very general and robust
and has been developed having in mind that GI2T/REGAIN should be used by
a wide community of astronomers.
