We created exclusive software for the reduction of the scanned plates of FON program for obtaining equatorial coordinates and U, B, V, R stars values of the detected objects. We reduced the scanned plates and compiled catalogues of positions and B values of the Kiev and Kitab parts of the FON which contain 19.5 and 13.4 billion of stars. In addition, the catalogues with 6820 positions and B(V) values of asteroids, komets, Pluto, and the satillites of the Solar system planets were created. We performed a series of high precision astrometric programs with the VLT and FORS2 camera and on the Gemini-South and Gemini-North with GMOS camera with aim to detect the satallites of the brown dwarfs, and to determine the orbital parameters and masses of the components of these systems. We detected four binary systems J0630014-184014, J0823031-491201, J1253108-570924, J1756296-451822 (designations from DENIS-P). For some of these objects and the binary systems Luhman 16 and GJ676A we determined parameters, the orbitall elements and masses. We observed occultation of the stars HD 45314 by the comet 21P and the star UCAC4-475-051755 by asteroid (259) Aleteja. The results were analyzed.  Product Description popup.authors Andruk Vitaly M.
