Road navigation using multiple dissimilar environmental features

May 23, 2017By

New navigation paradigms combining GNSS and inertial with additional sensors can increase overall reliability and power robust road navigation. A feasibility study tests a barometer, a magnetometer and a camera looking at road signs, and concludes that such sensors examining environmental features can supply the necessary context for frequently traveled or shared routes. read more

VectorNav supplies IMU for military bomb-disposal robot

May 11, 2017By

VectorNav Technologies, a provider of embedded navigation solutions, announced at AUVSI’s Xponential that it will supply its surface mount VN-100 inertial measurement unit/attitude and heading reference system (IMU/AHRS) to Neya Systems for a custom version of that company’s UxAB module. Neya Systems will in turn deliver its custom version of the UxAB platform to Northrop Grumman for that company’s Advance... read more

Expert Opinions: Integrity in the vehicle environment

January 23, 2017By

Q: Why do we need to take integrity seriously in the vehicle environment?   A: Since the 1980s, surveyors and geodesists have used GPS for high-accuracy positioning. We take for granted centimeter- and even millimeter-level accuracy positioning capability that is faster, more reliable, at a lower cost and with fewer constraints than ever before. However, the demand for “trustworthy positioning”... read more

HRL Labs to develop inertial sensor tech for DARPA

January 3, 2017By

The U.S. Defense Advanced Research Projects Agency (DARPA) has awarded HRL Laboratories LLC $4.3 million to develop vibration- and shock-tolerant inertial sensor technology that enables future system accuracy needs without using GPS. Positioning, navigation and timing are key to ensuring the location accuracy critical to the success of modern military missions. Today’s military systems typically rely on GPS to ensure position accuracy.... read more

When inertial can help with GNSS solutions

December 14, 2016By

A number of organizations are focusing on how inertial can help GNSS receivers to provide more stable, reliable position outputs when signals are hard to receive. Papers presented in September at the ION GNSS+ 2016 conference in Portland, Oregon, demonstrate that there is indeed a lot of focused effort in this area. The conference showcased several integrated inertial GNSS solutions from a... read more
