Cover Story

An Airborne Experimental Test Platform

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.

Michel Monnerat: Out of Africa — GNSS

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
Alenia Space.

Collective Detection of Multi-GNSS Signals

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.

GNSS in Military Affairs

(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?
