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…

The GBT Gain Curve at High Frequency

David T. Frayer, Frank Ghigo, Ronald J. Maddalena

Recent measurements at Q-band (43 GHz) have verified the improved performance of the GBT provided by the updated gravity model that was deployed in the fall of 2014. The measured g…

Skynet Algorithm for Single-Dish Radio Mapping I: Contaminant-Cleaning, Mapping, and Photometering Small-Scale Structures

J. R. Martin, D. E. Reichart, D. A. Dutton +22

We present a single-dish mapping algorithm with a number of advantages over traditional techniques. (1) Our algorithm makes use of weighted modeling, instead of weighted averaging,…

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…

Measuring and Correcting Wind-Induced Pointing Errors of the Green Bank Telescope Using an Optical Quadrant Detector

Paul Ries, Todd R. Hunter, Kim T. Constantikes +6

Wind-induced pointing errors are a serious concern for large-aperture high-frequency radio telescopes. In this paper, we describe the implementation of an optical quadrant detector…
