Atacama Large Millimetre Array (ALMA) project.

All the antennas will work together as if they were a single telescope, using the interferometry principle to provide spatial resolution ten times better than the Hubble space telescope.
Alcatel says the
project is a very daunting technical challenge, since the antenna surface accuracy must be within 25 microns, the pointing accuracy within 0.6 arc seconds, and the antennas must be able to be moved over a distance of 10 kilometres, and offer Sun-sighting capability. The observation array will cover more than 7,000 square metres.
