Some notes on the "FAKERAT" software. ... In 1989/1990 D.W.Murphy (JPL) added the VSOP spacecraft constraints since they have a major impact of the science return from this missions. The program with the spacecraft constraints and several additional features was subsequently renamed fakesat. ... We continued these developments by creating a new branch of the software connected with RadioAstron mission; we call this version as "FAKERAT". ... Therefore, fakesat orbit block was completely replaced. ...
