Mr. Molle,

Hello from Virginia, USA! I am a computer engineering student at Liberty University. Last semester, I built a UAV (thanks to all helpful info on this site!) and had a "successful" flight (more like it worked but the GPS was off and flew the plane into a tree for a not so graceful 50' drop onto its nose). This semester I am following your guide to build a boat that you wrote in your book. So far I have decided that for the sake of simplicity I am going to purchace a boat that is almost ready to run (just add the transmitter and batteries). My question is this: when I go to change the coordinates in the code you supplied, do I have to denote North, West with the coordinates in any particular way? the code is simply numbers. Positive and negatives perhaps? In any case I want to thank you for such an informative and useful chapter.
