We are working on a solar concentrator appliance. There is a picture of a similar dish here:

The dish must be aimed at the sun accurately, and we have sun position sensors to do that.
In addition, we want to record where the dish is aimed today, in case it is cloudy tomorrow. Tomorrow, if the clouds part suddenly, the dish needs to be pointed approximately right (so it will not take long for the sun position sensors and motors to move the dish into the right position).
A magnetic compass would work to sense the East-West orientation, and I found this thread:

We would also need to sense the tilt of the dish up and down. Could an electronic sensor also do that job?
Thanks,
