Radio Interferometry Applied to Geodesy

Mark II Minitrack, a basic type of radio interferometer, is used to obtain observational data from artificial earth satellites. It is assumed that the antenna field pattern can be approximated by a family of coaxial cones whose common apex is the electrical center of the system. The mathematical theory of calibrating the system with stellar radio sources and the reduction of satellite observational data is given, with an error analysis of the system.
