Advances in micro-electro-mechanical systems (MEMS) sensor technology include temperature-sensing MEMS oscillators (TSMO). Pairing a TSMO with a GNSS receiver, the authors successfully performed carrier-phase positioning and obtained accuracies better than typically required for automotive applications. MEMS oscillators can present space and cost advantages in integrated circuit assembly. By Bernhard M. Aumayer and Mark G. Petovello MEMS oscillators have found their... read more

PNT Roundup: STOIC technology to augment or substitute for GPS

November 11, 2015By
The X-47B unmanned combat aircraft receives fuel from an Omega K-707 tanker on April 22 while operating in the Atlantic Test Ranges over the Chesapeake Bay. This test marked the first time an unmanned aircraft refueled in flight. The X-47B is a tailless, jet-powered, blended-wing-body aircraft capable of semi-autonomous operation and aerial refueling.

The Defense Advanced Research Projects Agency (DARPA) selected Rockwell Collins to develop technologies that could serve as a backup to GPS. The research, being conducted as part of DARPA’s Spatial, Temporal and Orientation Information in Contested Environments (STOIC) program, aims to reduce warfighter dependence on GPS for modern military operations. read more

Xsens Adds Active Heading Stabilization to IMU

April 2, 2015By

In the latest update of its Motion Tracker product portfolio, Xsens has added active heading stabilization (AHS) to its core sensor fusion algorithms on the MTi 10-series and MTi 100-series. Both series are MEMS-based inertial measurement units (IMU), attitude and heading reference systems (AHRS), and vertical reference units (VRUs). The AHS algorithm delivers fundamentally improved heading tracking accuracy, Xsens said. The improved robustness in... read more
