Instrument Science Report FGS 2005-01 The FGS Astrometry in the Feb 2005 On-orbit Two Gyro Mode Test E. Nelan August 17, 2005 A BSTRACT FGS1r Astrometry was tested under the Two-Gyro Mode (TGM) pointing control law during the February 2005 on-orbit test. ... In each of these orbits the visit contained a single (long) exposure that observed the visit's particular target star for the remainder of the visibility period. ... Visit 02: Visit 02 employed a bright (V=9.9) dominant guide star. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... Next: Cheating Poisson: A Up: Statistical Analysis Previous: Spatial Models and . ... The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ...

... The distomats measure the average height of the platform every 2 minutes. If the average platform height is more than .04 inches from the nominal position, the tiedowns will pull (or release) equally on all 3 corners to bring the average height back to the nominal position. ... The platform corner height versus dome position (at fixed average platform height) shows that the platform corners move by +/- 6 inches just from the dome motion (this was before the alfa upgrade). ...
