Astrometry in Small Fields

Abstract

This report discusses the techniques and analysis for the precise reduction of the topocentric and apparent places of stars and artificial satellites. Included is a full discussion of the method of star constants, independent day numbers, geocentric parallax, parallactic refraction, and errors. Also described, in detail, is the analysis necessary for the real time modeling of the telescope-camera system, its theoretical basis, and differential reduction procedures. In addition, an original method for computing the distance of an artificial satellite from two measurements of position and one of angular velocity is developed. (Author)
