Abstract
This chapter summarizes the principles and tools of radio astronomy that ultimately lead to the establishment of a fundamental catalogue via application of the technique of radio interferometry to the measurement of positions of sources at cosmological distances. With this target in mind we briefly introduce the scope of radio astronomy, followed by a short outline concerning the basic terms and concepts of radio interferometry. We discuss the signal reduction from the observables of radio interferometry to astrometric quantities in some detail and, finally, consider the requirements for astrometry. At this point the stage is set for the establishment of a fundamental catalogue for use in astronomy and geodesy.
