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
