Hey.

Im writing an article about the basics of how a GPS system works, in terms of its communication and the trilateration process. Ive been able to explain the process with pictures really clearly in a 2D space, but im having trouble explaining it in a 3D plane with spheres.

Does anyone know where i can find a good video that visually explains the process which i can include in my article? There is a decent one on the howstuffworks website, but i cant use that directly in my article. Ive searched youtube but couldnt find anything.

Thanks in advance,
Dan.

Great Video.....I had to replay the bit about the intersecting spheres, but I got it in the end.
