Abstract
In November 2005 VertexRSI, a division of General Dynamics C4 Systems based in Kilgore, Texas, conducted site surveys on both a 7.2-m Ku-band antenna and an 11-m C-band antenna on Black Island, Antarctica. In addition to the site surveys, several photogrammetric surveys were performed on the 11-m antenna. The purpose of these measurements was to assess the geometric condition of the antenna structure so that several upgrade recommendations could be evaluated. What makes this project so intriguing is not just the measurement task itself, but the environment in which the measurements were conducted. This paper describes some of the challenges associated with performing this photogrammetric survey and operating photogrammetry equipment at temperatures less than –10° C. It will also explore ongoing testing where successful results have been obtained at even lower temperatures.
