Astrometric instrument modeling in the context of Gaia Astrometric Verification: tasks and activities. Proceedings of SPIE. 8449. 10.1117/12.926703. 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

The CCDs each are read out in TDI (time-delayed integration) mode, synchronised to the scanning motion of the satellite.

Astrometric instruments

Over the last 20 years, Astrometric products have been installed on hundreds of telescopes worldwide. Our customers include educational institutions, government organizations, privately funded observatories and telescope manufacturers. Astrometric Instruments offers standardized telescope control systems for custom applications. In 1995, we introduced our first telescope control system (TCS). Since then, our systems have been installed on hundreds of telescopes worldwide. 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.

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. How is all this possible?
