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

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

Kuwait high-rise goes up with assist from BeiDou

Kuwait-high-rise-Beidou-2

CORS station tracks China’s constellation over three frequencies. Headquarters for the National Bank of Kuwait, a new 300-meter-tall building under construction, combines concrete, steel, glazing and glass-reinforced concrete in a unique shellfish shape. The engineering challenges behind this building led the engineers of Ahmadiah Company, the contractor, to use GNSS technology to install the core wall structure with millimeter accuracy.... read more

Automotive nagivation suite.

Context-dependent scan matching for aided navigation By Jyh-Ching Juang, Shang-Lin Yu and Shun-Hung Chen Context-dependent scan matching for aided navigation — finding the rotation and translation that best align two consecutive scans — provides laser-ranging data that can be blended into a GNSS navigation system. A quality index based on analysis of intra-frame point clouds assesses the scan context, accounting for variations... read more
