Reply to "GPS in the News"

I read it to mean that the paper is irrelevant because "everyone knows GPS devices are not precise". Not that the paper was without merit, but that, to Grewal, this is not new information.

SPR has nothing to do with the point they are making in the article - that a GPS will consistently over-report the distance traveled. According to the article, if you ran the SPR, the GPS would still over-report the distance traveled.
