Use a photographic plate to record an image from a zenith-pointing telescope, and you will end up with a streaky image, as a result of the earth's rotation.
Data from a zenith-looking antenna of a space-borne GPS receiver are used mainly for precise orbit determination (POD) purposes, but here we used them in an implementation of the ROTI mapping approach.
Both methods do not correlate the reflected signal with a clean replica signal, but directly cross-correlate the line-of-sight signal received from a zenith-looking antenna either with the reflected signal from a nadir-looking antenna for the first method or with a modelled replica of the encrypted signal obtained in a semi-codeless way for the second method.
Following John Cheever's death from cancer in 1982, at the end of his life's work as a novelist and story maker, his reputation as a writer and human, despite his alcoholism — indeed abetted by his recovery from it — was at a zenith.
This patient cohort was supported, in part, by NIH grant AGO-8664 until 2000, and by a Zenith award from the Alzheimer's Association in 2002-2004.
His star is on the rise, following the release of his album Solid Air, while his friend Nick's is plummeting from a low zenith.
This study was supported by the Cynthia Woods Mitchell Endowed Research Fund, a Zenith Award from the Alzheimer's Association (RSD), and an unrestricted educational grant from the Forest Research Institute (SDR).
This research was supported by CTSA award UL1TR000445 from the National Center for Advancing Translational Sciences (E.A.E ., and NIH awards GM07628 (E.A.E ., MH073159 (R.D.B ., NIH/MLPCN grant U54 MH084659 (C.W.L ., and a Zenith Award from the Alzheimer's Foundation (R.D.B).
Observations from a GPS receiver with a zenith-looking antenna placed onboard a low earth orbit (LEO) satellite offer an opportunity to separate the ionospheric irregularities registered above a LEO from that on the ground.
A series of observations of the starry sky at different heights are carried out and by starting from the zenith with a telescope with larger field of view, the derivatives of various orders of atmospheric refraction function at different zenith distances are calculated and finally the actually observed values of atmospheric refraction can be found via numerical integration.
It is, after all, a love story in the form of a dictionary, with anecdotal entries from aberrant to zenith, only a handful of which are longer than a page.
