Frank Schlesinger, director emeritus of the Yale University Observatory, we have lost one of the great astronomers in the field of astrometry
The purpose of this document consist in describing and discussing the asteroids astrometry
program of the Astronomical Observatory of the Technological University of Pereira (OAUTP).
They used a technique called astrometry
to measure the stars' positions and were able to determine the stars' motions across the sky, their distances and whether or not each star had a hidden companion orbiting it.
(http://www.minorplanetcenter.net/mpec/K17/K17UI1.html) A notice by the Minor Planet Center on Wednesday which provided astrometry
data from the observations, said: "Further observations of this object are very much desired. Unless there are serious problems with much of the astrometry
listed below, strongly hyperbolic orbits are the only viable solutions.
"Gaia is at the forefront of astrometry
, charting the sky at precisions that have never been achieved before," Alvaro Gimenez, ESA's director of science, said in a statement.
Namely we use the combined solution of International VLBI Service for Astrometry
and Geodesy (IVS) ivs14q1X.eops (Schuh and Behrend, 2012).
This field of view was chosen deliberately to ensure that the images would contain a sufficient number of bright reference stars for the software algorithms to accurately and repeatedly produce results for the location of RSOs relative to the inertial reference frame provided by the background stars--a process known as astrometry
. From the astrometry-corrected images, topocentric right ascension and declination angles of detected RSOs are measured by using the highly precise positions of known background stars in the captured images.
Gaia is a space observatory of the European Space Agency designed for astrometry
"On an operational level, precise time and astrometry
can mean the difference between hitting the targeted building and hitting a building next door or in the next block," said Rear Adm.
Abstract: In this session we briefly cover the astrometry
principle of Gaia and the processing needed for it.
