OK, so assuming one independent measurement each second, the maximum error in each measurement is + or - 15 feet. It remains +/- 15 feet each time it is measured regardless of velocity.

So the maximum error after 1 second is 15 feet; after 2 seconds it is 15+15=30 feet; after 3 seconds 30+15 feet = 45 feet. It is t*(max error of one measurement). I am adding nothing for velocity, but I am assuming that the error occurs only along one axis (the track).
