Just days before the G20 Summit, Baker gained access to Pittsburgh Airport for an hour and a half. Using an escort vehicle, which maintained constant communication with Air Traffic Control, we surveyed two runways, several taxiways, approach lighting and the entire terminal. Our collection was highly successful. Due to the unobstructed sky, our GPS positioning yeilded constant accuracies of 8 - 12 mm for our trajectory utilizing a single base station.
To the left is an image showing intensity of runway 28L. There are two interesting components of this image. First, the bright dots to the left and right are field lights - their colored plastic lenses yeild higher intensity returns than their metal cases. Secondly, the rubber laid down by landing aircraft is clearly visible due, once again, to the intesity difference to the surrounding asphalt and white, reflective striping.
