This report describes the installation and results of a global calibration program introduced for both telescopes at the Lincoln Laboratory Experimental Test Site. The uncorrected positional pointing errors, due primarily to tube flexure, sag and astronomical refraction, were found to be as high as ten arc minutes at low (twenty degrees) elevation angles. The calibration is performed by a software program which contains look-up tables, for each telescope, that represent ...
This report describes the methods presently used to determine the position of the second Boller and Chivens telescope (telescope B) at the GEODSS ETS. Also discussed is a system devised for auto-calibration of the telescope position. (Author)
