Intercontinental Clock Syncronization with the Block I VLBI System
Abstract
The Block I Very Long Baseline Interferometer (VLBI) operated by the Deep Space Network (DSN) is used to make weekly measurements of the relative epoch and rate offsets between the time standards in the global network of DSN stations. Over the past year, the precision of these measurements has routinely achieved sub-microsecond levels for epoch offset and accuracies of better than one part in 10(exp 12) for rate offset. The implementation of the phase calibrator system will permit absolute measurement of epoch offset to better than 10 nanoseconds. With the near-real-time playback and on-line storage of VLBI data, the Block I system typically produces clock parameters within 48 hours from the time of observation.
