Got a neat applications question for you /sci/.

Ever heard of a Fresnel zone? It's an ellipsoid between two radio transmitters which graphs the trajectory of a radio frequency over a given distance.

What I know:
I'm working in GPS coordinates (decimal degrees). I know the distance between points A and B in meters. I know the radius of the Fresnel zone at any given point from start to end. I know the height of the Fresnel zone at any given point. I know it's bearing.

What I don't know:
What I need to do is plot the Zone in 3-D space. To do this, I have to get one thing, which is a set of 4 GPS coordinates, coordinates which will represent points along the circumference of the Zone at any given point of it's center of symmetry.

What I planned to do, but so far have failed, is to step to any point along the Zone, and pick a bearing, and walk out for the distance of the radius, then plot a point there. I may be failing because this is a bad plan, or because I am executing it poorly. Is it a bad plan?

I just failed Calc 2, and all I can think about is what the fuck do I need this stuff for in networking?

OP IS A FAGGOT
