It has recently become clear that the potential role of astrometry in cosmological studies has been underestimated. Some areas of cosmology that should be investigated using astrometrical methods are discussed. This paper is based on a presentation made at the conference “Modern Astrometry 2017,” dedicated to the memory of K.V.

Astrometry and Cosmology [PDF]
, 1974 For reference purposes, the earth’s surface at sea level may be represented by revolving an ellipse of eccentricity, e, and major axis, a e, about the polar axis. The flattening factor, f, or ellipticity, is related to the eccentricity, e,by the equation $${e^2} = 2f - {f^2}$$ (5-1) , The flattening factor is alternatively called the ...

Photographic Astrometry (Astrometrie Photographique)
1991Despite some much publicized disappointments, the highlights of Astrometry during the past three year period are dominated by the successful launches of the ESA 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 ...

The Physics Teacher, 2021
A question for science teachers during the pandemic is: how do we actively engage students in science, given that in-person instruction will be limited at best? One lesson I use for my solar system course involves naked-eye observations of positions of celestial objects. Such activities train students to take careful measurements, keep detailed records,

In Sect. 1.2, various objectives of astrometry were presented. Then, in subsequent chapters, the most effective Earth-based and space astrometric instruments in use were described. The question which now arises is: to what extent do they fulfil the above goals and what are the astronomical and astrophysical problems that require further advances in ...

Astrometry encompasses all that is necessary to provide the positions and motions of celestial bodies. This includes observational techniques, instrumentation, processing and analysis of observational data, reference systems and frames, and the resulting astronomical phenomena.

What is Astrometry? What are its objectives and its place in astronomy? By what means these goals are achieved? These are the questions that we are answering in this chapter before entering into the detailed description of the basic techniques of astrometry.
