Has anyone seen this amazing project where a small plane is supposed to fly
across the atlantic freaking ocean this week?
http://tam.plannet21.com/FAQs.htm#look
I noticed the guidance involves a Piezo Gyro. How do you think they keep
control of the gyro's drift due to temperature, natural gyro deficiencies
etc?
What I'm most interested in is the roll axis. I mean there is no dihedral
(wing bent-upward angle) to keep the plane from rolling, so a gyro must be
responsible for keeping the plane right-side-up in the roll axis for hours
and hours.
But dont those cheap piezo circuits have a slow drift? i.e. the plane is
level, but the circuit shows a slow rolling rotation at the rate of x
degrees per second? After a few hours (or even minutes) there would be
absolutely no accurate way of detirmining whether reported rotation rates
were drift or actual physical rotation.... how do you deal with this piezo
gyro drift in a system like this?
