On Two Color and CCD Methods for the Determination of Astronomic Position.
Abstract
The long range objective of the investigations in the area of astroposition consists of the application of new electrooptical techniques to obtain increased precision, accuracy, and effectiveness in the field operation of an astroposition instrument. The topics which are discussed in this paper relate to a portion of this program, that is, the design, construction, and use of the Two Color Refractometer (TCR). The purpose of this investigation of the TCR is to provide a series of corrections to the astroposition field measurements which would be made by a T-4 Theodolite or by an Astrolabe. These corrections address the errors caused by the refraction in the atmosphere. The corrections must be applied to the measured star coordinates in order to establish a more accurate value for the astronomic longitude and latitude.
