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…
Design and Performance of a Digital Phase Lock Loop for Gunn Oscillators
Todd R. Hunter, Robert Kimberk, Patrick Steve Leiker +2
The digital phase lock loop described in this paper has been in use on the Submillimeter Array (SMA) front-end receivers for over a decade and has been a key element in obtaining a…
