Global Navigation Satellite Systems Engineering, Policy, and Design
Members of Congress — who have not finished next year’s appropriations, face half a dozen major tax and program fixes set to expire, and have their own re-elections to worry about — must quickly decide how to handle a tsunami of federal budget cuts that experts say could sweep the economy back into recession.

Following a route defined by application requirements and remotely sensing the environment in order to analyze and interpret the outcome on- and off-line: this is the axioma of every aerial remote-sensing mission and, indeed, also for search missions. Yet, the specific requirements for navigation might vary according to the application.

University of Texas–Austin droneIn June a research team from the University of Texas at Austin (UT-Austin) demonstrated for the first time that a civilian unmanned aerial vehicle (UAV) can be commandeered in mid-flight by a civil GPS spoofing attack. The result will likely factor into the Federal Aviation Administration’s (FAA’s) plans to draw up rules for integrating UAVs into U.S. airspace by 2015.

Q: What are the tradeoffs between using L1-only and L1+L2 for PPP?
A: Precise point positioning (PPP) is a technique that can compute positions with a high accuracy anywhere on the globe using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be downloaded from the International GNSS Service (IGS) or obtained in real-time from a number of service providers, using either the Internet or satellite links.

Cloud computing opposite desktop software. The trend is predictable, yet it is always surprising when one technology takes over the market space of another. After all, television did kill off the radio star.

August 1994, early morning. Spain’s Central Pyrenees Mountains still in darkness.
At the outset of an ascent to a 3,000-meter peak along the international border, one of the co-authors encounters a group of tourist hikers who have begun searching for a colleague who had left the camp the previous evening. In the pre-sunrise gloom, helicopters cannot yet operate.
A week later, the body of the hiker is found. The rescue efforts came, unfortunately, too late.

ESA expert inspecting GIOVE-A in clean room in Baikonur Space Center, Kazakhstan. ESA photoWith the first two Galileo in-orbit validation (IOV) spacecraft working well, the European Space Agency (ESA) has decided to end the mission of its pioneering GIOVE-A satellite that had long exceeded it original purpose and design life.
Meanwhile, with the next Galileo launch approaching, ESA has expanded its Radio Navigation Laboratory (RNL) to meet the testing needs of Europe’s GNSS program.

[Updated July 2] Appropriators in both the U.S. House and Senate have slashed next year’s funding for support of the civil portion of the GPS program. Lawmakers halved the portion of the Federal Aviation Administration budget dedicated to supporting the civil signals as well as the ground network monitoring of those signals.

Leica Geosystems Mining and Locata Corporation will continue their exclusive technology partnership in the mine machine automation and mine fleet management markets until at least June 2014. The extension guarantees the ongoing, commercial provision to the global mining industry of the Leica Jigsaw Positioning System (Jps), powered by Locata technology.

Business School, University of Nottingham Jubilee CampusThe Royal Institute of Navigation will hold a new navigator seminar and networking opportunity at the University of Nottingham on June 14, 2012 for new navigators, engineers, scientists and surveyors who are seeking careers in the industry.
Masters and doctoral level students will present on navigation and positioning topics, advanced undergraduates and postdocs will be in attendance. A number of industry and government representatives will exhibit or attend to listen to new research and meet the new talent.

The European GNSS Agency (GSA) has published its second GNSS market report, including a special focus on maritime and surveying application markets and refining its projections of unit and sales revenue volumes through 2020.
According to the new GSA report, the worldwide GNSS market is growing rapidly with total market size expected to increase at an average of 13 percent per year until 2016. At that point, increasing market saturation, price erosion, and platform convergence will reduce the growth rate.
