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" dismisses such achievements, and the mantra is more "availability" and greater "integrity" to support highly automated driving. Our positioning and navigation community must rise to this challenge.
