I read with great enthusiasm Dee Ann Divis’ article New Chimera Signal Enhancement Could Spoof-Proof GPS Receivers. Logan Scott is one of the brightest people I know, and I very much enjoyed his presentation about Chimera last week at the National PNT Advisory Board’s public meeting in Alexandria, Virginia.

The deck of a tall ship rolled heavily beneath me as a freshening wind whistled through the rigging. A sextant in one hand and a stop watch in the other, I carefully listened. “Tock, Tock, Tock, Tock… the time is now fourteen hours, fifty-eight minutes, Coordinated Universal Time… Dong.” I clicked the stop watch in preparation for checking and winding the ship’s chronometers and measuring the height of the sun at local apparent noon.
