Astrometric Instruments, Inc. is a provider of premier electronics and software products for control of astronomical instrumentation. We have been designing and manufacturing custom astronomical instrumentation and control systems for over 20 years. The initial synthesis of Astrometric Instruments stemmed from a strong interest in astronomy and With this Astrometric Instruments went through an important transformation where our latest products are targeted for high-performance amateur and professional applications. While we remained interested in supplying observatory control solutions across the range from amateur to professional we no longer offered our commercial “retrofit” products for Losmandy and Celestron mounts.

Astrometric measurements are used by astrophysicists to constrain certain models in celestial mechanics. By measuring the velocities of pulsars, it is possible to put a limit on the asymmetry of supernova explosions. Also, astrometric results are used to determine the distribution of dark matter in the galaxy. The method of astrometric measurements by Gaia is described from first principles, and the fundamental limitations explained in terms of physics (diffraction and photon noise), geometry, temporal sampling and reference frames. ure 1), the astrometric instrument features (dimensions are along £ across scan): – two viewing directions separated by a basic angle of 99.4 deg; – each viewing direction with a pupil of 1.4 £ 0.5 m2; – a focal length of 46.7 m; – a beam combiner superposing the two fields on a sin-gle focal plane; Focal plane, containing the detector for the Astrometric instrument in light blue, Blue Photometer in dark blue, Red Photometer in red, and Radial Velocity Spectrometer in pink. Mirrors M4 and M'4, which combine the two incoming beams of light; Mirror M5; Mirror M6, which illuminates the focal plane Compared with Hipparcos, Gaia will give an enormous improvement in accuracy, completeness and number of stars: about two orders of magnitude in accuracy, four orders in number, and a completeness limit that is 12 magnitudes fainter.

Gaia’s main astrometric instrument precisely determines the positions of stars in the sky. By combining the measurements of any given star over the five-year mission, it will be possible to determine its parallax (and therefore its distance) and its proper motion (the velocity of the star as it moves on the plane of the sky).

The astrometric accuracy ranges from 10 μarcsec for bright objects to 200 This is necessary both in order to design the instrument so that these effects can be  Inom den adaptiva-optik instRUMENT, en snabb pockelscellen optisk Erickcek, A.

Gaia orbits at L2 and observes in two lines of sight (LOS), separated by a large angle (named "Basic Angle" (BA) and set to 106.5), continuously scanning the sky along a great circle and completing a rotation in 6 hours, i.e., a scan rate of 60 title = "The astrometric instrument of Gaia: Principles", abstract = "Compared with Hipparcos, Gaia will give an enormous improvement in accuracy, completeness and number of stars: about two orders of magnitude in accuracy, four orders in number, and a completeness limit that is 12 magnitudes fainter. The Astrometric Instrument Modelling (AIM) belongs to the Core Processing, or CU3, software systems devoted to astrometric data processing, instrumental monitoring and calibration.; it was About Astrometric Instruments builds control systems for telescopes and astronomical instrumentation. Further information can be seen at www.astrometric.com. We discuss the impact on the data quality and how the science data can be used to trace directly and in real time the astrometric instrument response of Gaia. This is one of the driver philosophies behind the Astrometric Instrument Model (AIM) concept.

The astrometric field in the focal plane is sampled by an array of 62 CCDs, each read out Gaia’s main astrometric instrument precisely determines the positions of stars in the sky. By combining the measurements of any given star over the five-year mission, it will be possible to determine its parallax (and therefore its distance) and its proper motion (the velocity of the star as it moves on the plane of the sky).
