Four Galileo ‘topped off’ for November launch

October 24, 2016By

Fueling operations have begun with the four Galileo spacecraft to be launched Nov. 17 from French Guiana. This will be launch contractor Arianespace’s first launch using its Ariane 5 rocket to deploy Europe’s constellation of navigation satellites. The fueling activity is now underway in the Spaceport’s S3B payload preparation facility. One of the first to be processed is named “Antonianna,” after an Italian child... read more

Yes, there are drones everywhere. Drones of every size from mini electronic insects to a rather nice Zeppelin remake that is cruising around Hall 4 at the Hamburg Messe. Will Intergeo 2016 mark “peak drone?” I’m thinking not. The two main drivers of this year’s Intergeo conference are digitization and smart data, including Building Information Modelling (BIM). Hamburg itself is... read more

Galileo Initial Services looming

September 26, 2016By

With Galileo Initial Services at last on the horizon and a quadruple satellite launch scheduled for November, here’s hoping that Europe’s GNSS constellation will be delivering limited, but reliable, global PNT services before the year is out. The four Galileo satellites for Arianespace’s first Ariane 5 mission for the constellation are being prepared at ESA’s launch facility in French Guiana.... read more

McMurdo launches emergency beacons with GPS, GLONASS, Galileo

September 7, 2016By
The McMurdo SmartFind and Kannad SafePro distress beacons support beacon transmission, GNSS for location positioning, and AIS for localized connectivity.

Emergency preparedness company McMurdo has launched a new family of Emergency Position Indicating Radio Beacons (EPIRBs) that will accelerate the search-and-rescue process by combining multiple frequencies — including GNSS — into a single EPIRB product. The McMurdo SmartFind and Kannad SafePro EPIRBs are distress beacons that can support each of the four frequencies used in the search-and-rescue process: GNSS for location positioning, 406 MHz and... read more
