From Theory to Flight: Part 2
Small UAVs can be used as a cost-effective platform for avionics development and testing. In the last issue, a research team based at the University of Minnesota–Twin Cities described their lab operations and how they use small UAVs to make aircraft safer and more fuel efficient. In this second part, they describe UAV test platforms for developing, testing and certifying new avionics and GNC algorithms for safety-critical systems.
Straddling two continents, French-born Michel Monnerat grew up in Togo,
loving math and science and playing soccer before sunrise. He grew up to
become an expert in Galileo signal design and a top engineer for Thales
Enabling New Smartphone Apps
With the integration of payment systems in the smartphones, location information could be used as a key authentication factor, relating user location with purchase events and helping to reduce fraud.
Vector-Acquisition Promises Sensitivity and Reliability Improvement
Vector acquisition collects all of the signals in a particular place, sorts out the weak ones, and identifies the best ones for navigation and positioning. This discussion describes a new methodology and implementation algorithm that uses multiple GNSS signals more effectively in signal-challenged environments.
Implementing Real Safety-of-Life Mandates
The idea of a federal agency requiring life-critical information be sent to state officials who have no plans for using it does not represent the finest moment for governance in America.
Hot spots in California, Florida, Tianjin, Kourou and the Antarctic
JPL uses GPS to find Sierra Nevada water weight; Near collision of drone and regional jet prompts questions, West Antarctic ice sheet melt at "point of no return," First Galileo FOC satellites at launch site, China's GBAS tested in Tianjin
(And Vice Versa)
Born in the depths of the Cold War, the Global Positioning System pioneered a long and winding road to its preeminent status in myriad civilian uses. But it began — and continues — as a quintessentially military utility. What’s that mean in today’s world?
