TOOLS OF TEST GENERATION FOR SATELLITES CONTROL PROGRAMS Andrey Tyugashev, Ekaterina Myasnikova, Elena Sopchenko S.P. Korolyov Samara State Aerospace University (National Reseach University) The paper presents a research in the field of test automation for testing spacecraft control programs. ... Programmers or designers of spacecraft systems write tests manually. ... Tests are carried out by issuing the control actions on the spacecraft and condition monitoring systems parameters of the spacecraft. ...

... 8, ``Celestial Mechanics'', 2002 High precision parallel algorithms of numerical integration of celestial mechanics problems N. V. Batkhina, A. B. Batkhin Volzhsky Institute of Humanities, Volgograd State University, Volzhsky, Russia We investigate different scenarios of dynamical chaos origin in Hamiltonian systems generated by some celestial mechanics problems. ... 22 We compiled these algorithms to C programming language with free multiple precision library GMP (GNU MP library) [5]. ...

... Expected NICMOS Performance after HST Servicing Mission 3 . NICMOS Cooling System Design . ... NASA is developing the NICMOS Cooling System (NCS) to provide operation of NICMOS beyond the exhaustion of its stored solid nitrogen cryogen. ... The NCS combines an external radiator identical in design to the ACS/STIS Aft Shroud Cooling System (ASCS) planned for SM3, a Creare, Inc. reverse-Brayton cycle turbine cooler, and an EVA installed neon loop to the NICMOS dewar's cooling coil. ...

. You can compare any two versions of a file that is under the control of SCCS with the sccsdiff command: /usr/sccs/sccsdiff -r version -r version s. filename . Using this command produces a line by line difference between the two versions of the file. Results are shown in the same format as that produced by the diff command. Examples .
