Reach and Canon CHDK

I’d like to know if it’s possible to use a Reach to log precise image locations using CHDK Wiki | Fandom. I’d like to set this up on my Tuffwing UAV Mapper to eliminate the need for ground control points.

Yes, it is possible. Reach has spare GPIO that could be used to trigger the camera. You will need to connect flash sync signal to reach time mark input in order to get precise locations.

This is great news.
I realise that you guys are flat out getting your product out but do you think you would be able to do a quick tutorial down the track?
