Intelligent transportation systems require ‘the ego vehicle’

May 8, 2017By

Most activity so far in the PNT community has centered around the questions of “Where am I?” and “Where am I going?” and “How fast am I going?” Positioning, navigation and timing. Seemingly that should about cover it. But no. Mapping comes into the picture: “What fixed objects are in my environment?” This is actually a corollary of “Where am... 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
