Flowdown of the TMT astrometry error budget(s) to the IRIS design [PDF]
, 2016 TMT has defined the accuracy to be achieved for both absolute and differential astrometry in its top-level requirements documents. Because of the complexities of different types of astrometric observations, these requirements cannot be used to specify ...

Reference-less detection, astrometry, and photometry of faint companions with adaptive optics [PDF]
, 2009 We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms exploit the difference in statistics between the on-axis and off-axis intensity.

SST Anywhere—A Portable Solution for Wide Field Low Earth Orbit Surveillance
Remote Sensing, 2022 The low-Earth orbit (LEO) is filled with active satellites, but also with space debris, which need constant observation. The orbiting objects may be affected by collisions or by atmospheric drag, and therefore they can change their orbit or even fall to ...

Photographic zenith tubes observations to improve HIPPARCOS proper motion in declination of some stars [PDF]
Serbian Astronomical Journal, 2005 A procedure of calculation and results of an attempt to improve proper motions in declination for some HIPPARCOS stars are presented. A long series of optical observations of these stars observed with Photographic Zenith Tubes (PZT) are used.

24. Photographic Astrometry (Astrometrie Photographioue) [PDF]
Transactions of the International Astronomical Union, 1991 Despite some much publicized disappointments, the highlights of Astrometry during the past three year period are dominated by the successful launches of the ES A Hipparcos astrometric satellite and the NASA Hubble Space Telescope. For the past 15 to 20 years the research activities of many Commission members have been monopolized by the design and ...
