Source Structure Errors in Clocks by Radio the Synchronization of Interferometry

J.B. Thomas

Abstract:	Radio interferometry has the potential of synchronizing clocks across intercontinental distances with accuracies better than one nanosecond. One of the potential error sources in such determinations is the spatial structure of the natural radio sources that provide the reference signals. Due to their extent, the effective position of these sources can vary as a function of the length and orientation of the baseline vector joining the two antennas. If they are not corrected, such variations can lead to errors in clock synchronization. This presentation discusses the theory of structure corrections and gives specific examples to illustrate the nature and size of the effect.
