Not sure if this is the right place to post.
We are testing the SF02 laser for auto landing and have it working and communicating and are now trying to implement into Arduplane code.
It looks like the altitude is updated through update_alt, but it is only looking at the barometer. Does anyone know if and where the code checks the GPS Altitude? I seem to remember a couple of lines that say;
If the GPS is valid and it has a good fix, use GPS altitude. If not, use baro altitude.
