Astrometrical software at the Pulkovo Observatory

Abstract

Modern computing techniques are widely used in astrometry for reduction of astrometrical observations, theoretical studies and for gathering and storing measurements and observational data. At present the Pulkovo Observatory has a 3rdgeneration Soviet-Bulgarian computer ES-1020. It is similar to IBM computers in programming languages, magnete tapes, punch-cards and formats. ES-1020 can be used for a single-program and concurrent processing because it is supplied with a disc operating system(DOS). As its components DOS has the following translators: ASSEMBLER, BASIC, FORTRAN IV, PL/1, COBOL, etc., and also a programming library of mathematical and astrometrical modules. The library of sub-routines has a module principle which permits changing its contents and including new modules, e.g. astronomical programs.
