Galileo Success, Flexibility, and a Look Ahead

Miguel Manteiga Bautista

The first generation of the Galileo Program, at satellite and ground segment level, has been “an enormous success,” according to Miguel Manteiga Bautista, who recently spoke with Inside GNSS at his office at the European Space Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk, Netherlands.

Defeating ‘Death by GPS’

Park rangers in Death Valley National Park have begun calling it “death by GPS.” Visitors faithfully following their navigation devices turn down the wrong road or hike away from help and die before rangers can reach them.

But it really isn’t the GPS, it’s the maps in their navigation system’s database.

COMPASS POINTS

GNSS event that most signified to you that GNSS had ‘arrived’

Testing of the initial handheld units from vendors such as Trimble’s two-channel GPS receiver and Rockwell Collins’ PLGR. “We thought, ‘What an amazing capability to have a handheld device that all you had to do was turn it on and it told you where you were – wow!’”

>>Jade Morton’s Compass Points

Yu — or Jade, in English — Morton is an electrical engineer, a professor at Colorado State University (bound for the University of Colorado Boulder in 2017), and a shining star in the world of GNSS. She left work for eight years to be a full-time mother, then returned to a university professorship and high-level research, where she has been recognized for her work on ionospheric effects on global navigation satellite systems.

The “Brussels View” from Prague

Carlo des Dorides, GSA Executive Director

Last October, the European GNSS Agency (GSA) Administrative Board reelected Carlo des Dorides as executive director of the GSA, giving him a second — and final — four-year term in charge of this key agency responsible for supporting the effective operation, maintenance, and security of Europe’s satellite navigation systems. We met with him recently at the GSA office in Prague to learn how he plans to see out his mandate.

Military GPS Receiver Advances Could Help Trim Satellite Costs

Advanced military receivers using the sort of modern multi-channel, multi-constellation capabilities already available commercially, could enable the Air Force to focus its anti-jam efforts on the ground, simplifying future GPS satellites and lowering their cost. Moreover, experts told Inside GNSS, the cutting-edge receivers could be deployed years before the anti-jam capability planned for the new GPS III satellites would be fully available.

Sandy Kennedy: Here to Stay

Sandy Kennedy and her husband Arlin Amundrud

>>Sandy Kennedy’s Compass Points

Sandy Kennedy grew up in Miami. Miami, Manitoba, Canada, that is — a town of 150 people with a school, a café, a defunct railroad station, and an ice skating rink.

Now she’s director and chief engineer in charge of receiver core cards at NovAtel Inc., a developer and manufacturer of high-precision GNSS products headquartered in Calgary, Alberta. It’s a long way from where she started, but then again, maybe not.
