Demo models from the Institute of Navigation's first Mini-Urban Challenge, a contest among high school students for miniature autonomous vehicles, took the center ring on the floor at the ION GNSS Exhibition. High school students worked in teams of 3 to 10 to design and operate a robotic unmanned...More>>

Miniature autonomous vehicles navigating the mean streets of a LEGO town take center stage at the show floor at ION GNSS 2009.More>>

A system being tested could someday enable emergency and military crews to precisely pinpoint their on-foot navigation, using a network of sensors worn by individuals.More>>

A tightly coupled solution that combines measurements of GPS, two-dimensional laser scanner, and inertial sensors for trajectory reconstruction estimates the user delta position between consecutive update epochs. Example applications that would benefit from accurate trajectory reconstruction...More>>

Integration of GPS and wireless high-speed communications in vehicle-to-vehicle and vehicle-to-roadside links can reduce accident rates and injuries. A sophisticated processor, GPS receiver, and dedicated short-range communications (DSRC) transceiver tap into available sensors that already help to...More>>

Preplanning information about terrain is as important as real-time navigation for achieving peak performance in autonomous driving. Both preplanning and navigation — and key technologies to support them — helped the Carnegie Mellon Red Team successfully guide the robot vehicles Sandstorm and...More>>

The Defense Advanced Research Projects Agency (DARPA) will hold its third Grand Challenge in a mock urban area, upping the ante and the technical difficulty from previous robotic vehicle challenges staged in mountain desert terrain.More>>

Collaborative driving systems — linking several vehicles together using in-vehicle positioning and control systems — can increase road capacity, improve safety, and reduce driver fatigue and stress. This test used fixed-ambiguity carrier-phase GPS as the primary sensor, with a digital camera...More>>

The emerging market for autonomous vehicles got a huge lift in January, when a heavy truck navigated its own way through a proving grounds with no human input, showcasing an application for the U.S. Army vehicle fleet.More>>

New MiniSAR aids motion compensation, photogrammetry, autonomous vehicle navigation, and aerodynamic modeling.More>>
