Calibration of the interferometer
Abstract
A survey of external calibration of the satellite orbit determination interferometer system is presented. This external calibration is necessary to determine all system errors not covered by internal calibration, e.g., in the antenna system. A source of errors is the position of the antenna phase centers and their possible displacements as a function of observation direction.
