You may have seen some Galileo images with black stripes cutting across them . This indicates that during the transmission, one or several of the antennas was off source, but the data loss was not deemed serious enough to warrant re-transmitting the missing frames. The new aerial cabin being installed. The old cabin is in the foreground resembling a lunar module. This new aerial cabin can hold four receiver packages instead of, as in the old focus cabin, just one, and any of them can be swung into action within minutes.
Radio astronomers can also use it for many other diverse astronomical observations.
The construction of the new aerial cabin was completed in early 1996, and the first test track was made in March. The contracted tracking ran from 28 October 1996 to 6 November 1997 for about nine hours each day. Dr Ian Stewart, Mr Russell Pace and Mr John Sarkissian with occasional help from other observatory staff. As the seasons changed, the starting times of the daily nine-hour tracks slowly migrated through the day. Over the year, the tracks shifted from being wholly in daylight to wholly at night.
