I know javascript, html, css, and a decent amount of jquery. I don't know what your problem is exactly, as you didn't explain it very well. However, I saw something with trajectories, longitudes, and lattitudes, and was figuring I would at least have the trigonometry/math for it.
I also put the time at 3 days because I don't know what bugs you have, so it might not be a 1 day thing, and I don't have a full day tomorrow anyway.
