For the last 7 years we have been developing a 3-telescopes breadboard of the SOLARNET imaging interferometer proposed to CNES (French National Space Agency) for a possible Space Mission as early as 2010 (new start expected in 2006). After having been successfully tested in laboratory for phase control (up to λ/300) and interferometric direct imaging performances, the setup was moved to Meudon Observatory at the "Grand Sidérostat de Foucault" in 2000 for direct testing on the Sun. Following the implementation of an automatic guiding and dedicated fine pointing for each telescope (capable of one twentieth of an arcsec), the complete interferometric setup is now nearly ready to observe properly in a coordinated cophased and copointed mode and to acquire its first images. We report the progress achieved in developing the breadboard and its spectro-imaging capabilities (a subtractive double monochromator), and indicate what are the next possible steps and prospects of the SOLARNET program both on ground and in Space.
