As you might expect, acquiring a signal from a satellite traveling at speeds of over 17,400 mph can be a tricky business. A new system called SARAS, which is a Spanish acronym for "Fast Acquisition of Satellites and Launchers," more than doubles the effective area of the receiving dish antenna, allowing the signal to be acquired much faster.
