From: "Taking Position: Solving PNT Problems on Mars" (http://gpsworld.com/taking-position-solving-pnt-problems-on-mars/) "One sequence in the book describes Watney's ingenuity in solving a navigation problem in a truly GPS-denied environment, with only the limited supplies he has on hand. I don't want to spoil anything, but I will say that the solution includes old-school triangulation, with a few twists. With a fierce dust storm bearing down on him, Watney employs his knowledge of position, navigation and timing to aid in his own rescue. I was reminded of this as we at GPS World embark on our own adventure, reimagining our scope to include PNT and other location technologies. GPS, while still in our name, is far from the only solution. "While the movie is excellent, I suggest anyone who's fascinated by the science in fiction pick up a copy of the novel that inspired it." -- Richard Langley ----------------------------------------------------------------------------- | Richard B.
