On the Adoption of a Terrestrial Reference Frame
The report of the IAU Working Group on Nutation endorsed by Commissions 4, 8, 19 and 31 at the 1979 General Assembly points out that "... the complete theory of the general nutational motion of the Earth about its center of mass may be described by the sum of two components, astronomical nutation, commonly referred to as nutation, which is nutation with respect to a space-fixed coordinate syste...
متن کاملDORIS satellite phase center determination and consequences on the derived scale of the Terrestrial Reference Frame
We analyzed one year of DORIS data to estimate daily corrections to the mean locations of the satellite antenna phase centers. For each DORIS satellite, we looked for possible biases, discontinuities, trends or annual signals. All SPOT satellites show very similar patterns, which are characterized by a significant constant bias of about 20 mm in the cross-track direction as well as a clear annu...
متن کاملTerrestrial Reference Frame Requirements for Studies of Geodynamics and Climate Change
Scientific applications critically depend on the ITRF and impose the most stringent requirements on terrestrial reference frame accuracy and long-term stability. A recent US National Research Council report (Minster et al., Precise geodetic infrastructure: national requirements for a shared resource. The National Academies Press, Washington, DC, 2010) found that the applications demanding the h...
متن کاملThe reference frame of the motion aftereffect
Although eye-, headand body-movements can produce large-scale translations of the visual input on the retina, perception is notable for its spatiotemporal continuity. The visual system might achieve this by the creation of a detailed map in world coordinatesVa spatiotopic representation. We tested the coordinate system of the motion aftereffect by adapting observers to translational motion and ...
متن کاملThe reference frame of the tilt aftereffect.
Perceptual aftereffects provide a sensitive tool to investigate the influence of eye and head position on visual processing. There have been recent indications that the TAE is remapped around the time of a saccade to remain aligned to the adapting location in the world. Here, we investigate the spatial frame of reference of the TAE by independently manipulating retinal position, gaze orientatio...
