Mark 6 VLBI Data Recording System Overview

 

The Mark 6 VLBI Data Recording System is a vital tool in Very Long Baseline Interferometry (VLBI), a technique used for high-precision astronomical observations. VLBI allows for extremely high-resolution measurements of radio sources such as quasars, black holes, and other celestial phenomena. By using multiple radio telescopes distributed across vast distances, VLBI simulates a single, much larger telescope. The Mark 6 system records, synchronizes, stores, and processes the data collected by these telescopes, enabling precise and detailed images and measurements of the universe.

Why the Mark 6 is the Premier Global Standard for VLBI Data Recording System?
