What have you been up to in the world of PNT?

March 29, 2017By

Do anything interesting today? Specifically, did you do something interesting involving positioning, navigation or timing (PNT)? GPS World is always on the look-out for case studies — stories of how you, our readers, used PNT or GNSS equipment, or applied related technologies, to solve a problem. Each month in our Market Watch and Updates sections, I try to include a... read more

Expert Opinions: Integrity in the vehicle environment

January 23, 2017By
Chris Rizos, Professor, Geodesy and Navigation, 
University of New South Wales

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
