International Global Navigation Satellite Systems Service (IGS) let users of satellite navigation systems free access to the information of rather precise coordinates of every satellite in Greenwich coordinate system with two week delay. ... As a result of applying this algorithm the trajectory of every satellite was defined as precise as IGS data. ...

The stars evolution is a change with a caurse of time the physical characteristics and the cemical composition of the stars. The stars evolution on the base of physical characteristics composition is investigated when the stars are at the different steps of evolution. ... The star evolution is going in the compact double star system in its own ways. Back . ...

The revision of the MASS/DIMM star catalogue N. Shatsky, V. Kornilov March 16, 2008 Abstract The compilation of the (updated) version of the MASS (MASS/DIMM) device target catalogue is described. ... Then the list was cleaned according to following criteria: I. Remove stars too faint for a MASS device. ... Here the color equation of the Sternb erg device was taken: M AS S mag = V mag + 0.45 (B - V ); stars with M AS S mag > 3.2 were removed. ... This was made based on the GCVS4.2 catalogue data. ...

The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...
