"If you go the blimp route you could probably make an electronic anchor. The anchor would be on ~200ft of cable and would start out as a cylinder. When it's time to stop, the blimp just drops the anchor, and it plunges into the cannopy. When it…"

"You'll need to have a TV tuner card if you want to hook up AV to a computer. Alternately, you could try one of these: http://brilldea.com/product_30LCDanddriver.html I've used one before, and it's pretty nice."

"A good place to start would be a general purpose programming language book. C++ or Java would be good (I particularly like "Programming Principles and Practice Using C++" by Bjarne Stroustrup). The advantage by learning a high level…"

"GPS speed (and heading) are calculated from taking sequential recordings of the location (lat and long) and comparing them. Since lat and long are 2D, it follows that speed (and heading) are also 2D."

"For the video problem you mentioned earlier. You don't need to review an hour of tape every day. Since the gates don't move (they have a fixed coordinate) you can just have the UAV take a single photo of the coordinate, then review that…"

"Here's a link to some code on how to calculate a heading based on two GPS coordinates. It's made for the multiple slot BS2s since it takes quite a bit of code to work around the 16 bit processor. I haven't tested it in any sort of…"
