Cover Story

From Fledgling to Flight

Boeing's Little Bird UAV

For several years now, a Boeing engineering team has examined various methods for navigating a vertical takeoff and landing of an unmanned aerial system to a moving vessel for launch and recovery. The team developed and tested a GNSS/inertial system that uses relatie navigation techniques to do this successfully.

A Collaborative GNSS Receiver Architecture for Weak Signal Processing

There are lots of ways to enhance single-receiver GNSS navigation performance. However,
methods that combine data from multiple receivers remain relatively unexplored. A new
receiver design takes advantage of the untapped potential for collaborative approaches to achieve more robust positioning capability, particularly in weak signal environments.

In-Car GNSS Jammer Localization Using Vehicular Ad-Hoc Networks

It’s an exciting idea: Use vehicular ad-hoc networks to locate in-car jammers. Theoretical and experimental results confirm that localization based on this approach has an error below 40 meters — that’s sufficient accuracy for determining the origin of an interference source.
