Green Bank Telescope: Overview and analysis of metrology systems and pointing performance
E. White, F. D. Ghigo, R. M. Prestage +7
With a 100mx110m off-axis paraboloid dish, the Green Bank Telescope (GBT) is the largest fully steerable radio telescope on Earth. A major challenge facing large ground-based radio…
Commissioning the HI Observing Mode of the Beamformer for the Cryogenically Cooled Focal L-band Array for the GBT (FLAG)
N. M. Pingel, D. J. Pisano, M. Ruzindana +19
We present the results of commissioning observations for a new digital beamforming back end for the Focal plane L-band Array for the Robert C. Byrd Green Bank Telescope (FLAG), a c…
Performance of a highly sensitive, 19-element, dual-polarization, cryogenic L-band Phased Array Feed on the Green Bank Telescope
D. Anish Roshi, W. Shillue, B. Simon +26
A new 1.4 GHz 19-element, dual-polarization, cryogenic phased array feed (PAF) radio astronomy receiver has been developed for the Robert C. Byrd Green Bank Telescope (GBT) as part…
A Highly-Sensitive Cryogenic Phased Array Feed for the Green Bank Telescope
D. Anish Roshi, W. Shillue, J. R. Fisher +15
In this paper, we describe the development of a new L-band (1.4 GHz) Cryogenic Phased Array Feed (PAF) system, referred to as the GBT2 array. Results from initial measurements made…
Holographic Measurement and Improvement of the Green Bank Telescope Surface
Todd R. Hunter, Frederic R. Schwab, Steven D. White +11
We describe the successful design, implementation, and operation of a 12 GHz holography system installed on the Robert C. Byrd Green Bank Telescope (GBT). We have used a geostation…
