Global Navigation Satellite Systems Engineering, Policy, and Design
The Air Force is scouring the landscape for its next round of receiver technology now that the first increment of its military receiver development program is moving into a deeper testing phase.

In the past two decades, satellite navigation systems have undergone great development. The development of new generations of global navigation satellite systems (GNSS), represented by GPS III, Galileo, and the BeiDou global system (BDS), is rapidly advancing.

All good things must come to an end. At which point, if Fortune smiles on us, other good things begin or continue.
Case in point: as of year-end 2017 I am promoting myself to Editor Emeritus of Inside GNSS and turning to some unfinished business that I have with life. Of course, after 28 years I still have some unfinished business with GNSS, this amazing technology and industry that has more growth ahead of than behind it, more prospects for innovation, more unfinished business than ever.

At the lavish European Satellite Navigation Competition Awards Ceremony, we caught up with Carlo des Dorides, general director of the European GNSS Agency (GSA), who updated us on the status of the much-anticipated Galileo Commercial Service (CS).
“On the CS, we are dialoging extensively with EU member states, because there is a more and more consolidated view that there could be an advantage to providing the service for free,” des Dorides said.
