Tomorrow’s driverless convoy on the road today

June 6, 2016By
Convoy-opening-W

Unmanned tactical wheeled vehicles for logistics and route clearance missions provide a significant force protection advantage — removing personnel from targeted vehicles, extending standoff distance from explosives, and empowering a single operator to simultaneously supervise multiple unmanned assets in convoy. This article discusses some of the enabling technologies and the motivations behind them, for safer and more efficient logistics and... read more

Congress Yanks OCX Funding SecDef Must Demonstrate Its Essential Nature The U.S. Senate Armed Services Committee withheld the full amount requested by the Pentagon for Fiscal Year (FY) 2017 for OCX, the Next-Generation Operational Control System (ground control) for GPS, heretofore deemed necessary to operate the next generation of satellites, GPS III. The Pentagon had asked for $394 million in... read more

Self-driving cars need FOG, inertial

May 18, 2016By

New products come to market poised for take-off Fiber-optic gyros (FOGs) and FOG-based inertial measurement units (IMUs) form key parts of the integrated sensor systems essential for highly accurate autonomous car performance. For example, FOGs provide precise azimuth measurements that an autonomous car’s logic processing unit and control systems need to determine motion through a curve. An IMU — which... read more

Is reliance on GPS making us lose our mapping minds?

May 16, 2016By

By Tracy Cozzens Managing Editor I love maps. As a child, I was my family’s designated navigator on car trips (or my parents indulged me!). I studied our roadmaps, searching out each legend icon on the map and finding icons to look up on the legend. I would use the map’s indicators to determine the distance between points and interesting... read more

Research Online: Laser localization system implementation, UAS sense and avoid integrity

May 13, 2016By

Implementation of a Laser Localization System By Aidan F. Browne and David Vutetakis, The University of North Carolina at Charlotte. Presented at IEEE/ION PLANS 2016 in Savannah, Georgia. A novel laser-beacon localization system has been developed that has applications in positioning and navigation of mobile ground or aerial vehicles where other forms of localization are absent (such as GPS). The... read more

UAV achieves full-speed autonomous landing

In the most critical phase of the landing maneuver, the UAV flight control system must compensate for the accelerated air flow above the ground vehicle. (Photo: DLR)

Moving at 75 kilometers an hour (47 mph) an unmanned, electric, autonomous aircraft settled gently on the roof of a moving car. Scientists from the German Aerospace Center (DLR) Institute of Robotics and Mechatronics combined robotics and unmanned aerial vehicles (UAVs) to develop a system where a fixed-wing aircraft automatically lands on a moving ground vehicle. The DLR system is... read more

By Chaminda Basnayake RENESAS Electronics America Inc. Recent progress with Dedicated Short Range Communications (DSRC) Notice of Proposed Rule Making (NPRM) brings connected cars or V2X — connectivity between vehicles, infrastructure and all road users — closer to reality than ever before. If all goes well, an NHTSA mandate on DSRC in new light vehicles is expected to start around 2020... read more
