First of all, thanks for that great script and idea. This is inspirating.
I hope it´s ok that I try around with your tool and alternate a little bit. If not, let me know and I´ll stop it.

I was trying to use your script to create a guidance system for missiles, using the sekstant twice on 2 points of the ship (to use the system without moving).

I took a screenshot to show you.

Both "Sensors" have their own GPSTop, GPSLeft and GPSRight named GPS1Top, GPS2Top, ...
When hitting PB1, the first coordinates show up on TPData, but when I hit PB2 nothing happens.

Any ideas ?
