UAVs: Sharing the Airspace is the topic of this one-day workshop on February 12 at the National Physical Laboratories, Teddington. It is part of the Royal Institute of Navigation’s NAV series of conferences.
Unmanned and manned aircraft will operate together in the skies in the very near future. How will that work?
Topics include:

One in a series of NAV conferences sponsored by the Royal Institute of Navigation, this all-day event on February 21, 2013 will take place at Southampton Solent University Conference Center.
NAV-Maritime will focus on:
• Is ECDIS letting us down?
• The role of integrated navigation systems (INS) within e-navigation
• The increasing interest in unmanned vessels
Legal filings suggest the U.S and the United Kingdom may be well on their way to working through a heated dispute over patents that, if left unresolved, could scuttle efforts to make GPS and Galileo interoperable.

A Soyuz rocket lifts off from Europe’s spaceport in French Guinana on its mission to place the second pair of Galileo in-orbit validation satellites into orbit. ESA photo by S. Corvaja.[Updated October 26, 2012] A Soyuz ST-B launcher carrying two Galileo in-orbit validation (IOV) satellites took off as scheduled at 18:15 GMT (20:15 CEST; 2:15 p.m. EDT) on October 12 from the European Spaceport in French Guiana.
All the stages of the Soyuz vehicle performed as planned and the Fregat-MT upper stage released the Galileo satellites into their targeted orbit close to 23,200 kilometer altitude, three hours 45 minutes after liftoff.
