Global Navigation Satellite Systems Engineering, Policy, and Design
One of my fond memories as a boy growing up in rural northeastern Oregon is sitting on an apple box in the basement of our house reading back issues of National Geographic.
All those wonderful color photos. And the maps, with their little illustrated explanations of Roman ruins in England or Babylonian irrigation practices in the Fertile Crescent!

eCall is the European Union (EU) initiative aimed at reducing road casualties by increasing the speed and efficiency of emergency response. It involves a device installed in cars that will automatically dial the EU’s “112” emergency phone number in the event of a serious road accident.
Key data including time, date, and GNSS coordinates will be sent to the Public Safety Answering Point (PSAP) and then relayed to the most appropriate emergency service. The eCall is triggered by airbag deployment and impact sensor information.

This course on modern GNSS, positioning and timing applications takes pace at Aalborg University in Denmark from noon on May 15 until noon at May 17.
Thee free three-day program is open to doctoral students working in GNSS or related areas at a European university.
The lecturers and topics are:

Working Papers explore the
technical and scientific themes that underpin GNSS programs and
applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
Veth proudly poses with his RV-8A fuselage components securely fastened in a jig. The RV-8A is a two-place, tandem, experimental aircraft that is home-built from kit components. When completed, he plans to use the aircraft as an experimental navigation testbed.SIDEBAR: Mike Veth’s Compass Points
Over the course of Lt. Col. Michael Veth’s 20-year career in the U.S. Air Force (USAF), certain navigation technologies may have changed dramatically, but working toward increased accuracy has remained a constant.

Anyone who has gone to college is probably familiar with the idea of a capstone course. A final hurdle to clear in receiving a degree, students take such a course to demonstrate their practical knowledge by pulling together all of the main concepts taught throughout the program of study.

FIGURE 1: Potential components of a multisensor integrated navigation systemThe navigation world is booming with new ideas at the moment to meet some of the greatest positioning challenges of our times. To realize demanding applications — such as reliable pedestrian navigation, lane identification, and robustness against interference, jamming and spoofing — we need to bring these different ideas together.

Allure Shadow (top), structural clearances (bottom)The Boeing Company initiated the Unmanned Little Bird (ULB) program in the fall of 2003 to create a developmental platform for an optionally manned, vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV). Initial flight test activity employed a modified MD530FF helicopter, with the first flight taking place on September 8, 2004. Six weeks later the program achieved a fully autonomous multiple waypoint demonstration flight from takeoff through landing.

Deep military spending cuts set to kick in March 1 will likely slow efforts to modernize the GPS constellation, insiders agree, in large part because many of the personnel needed to push the program forward will be sitting at home, unpaid, one day out of every five.
The human impact of the deep cuts taking effect when sequestration kicks in on Friday was already evident in mid-February during the program review conference held by the Association for Unmanned Vehicle Systems International.

The Air Force will put the navigation message onto the civil L2C signal as part of a test it plans to conduct this summer, sources have told Inside GNSS.
The test will take place over a two-week period in June and will involve all of the satellites capable of broadcasting the signal.

The core structure of the GPS III Non-Flight Satellite Testbed (GNST) stands in Lockheed Martin’s GPS III Processing Facility. Lockheed Martin photoWell, the lights work. So far, so good.
The Lockheed Martin team developing the U.S. Air Force’s next-generation GPS III satellites has turned on power to the system module of the program’s first spacecraft, designated GPS III Space Vehicle One (SV-1).
According to the prime contractor, the achievement is a key indication that the team is on track to deliver the first satellite for launch availability next year, although the actual first launch will probably take place in 2015.
