Hi all,
I'm about to start a project on making my first autopilot! From what I've read so far, thermopiles are fairly accurate and not susceptible to noise such as vibration whereas the IMU is. However, from most autopilots that I've seen, neither are used together for attitude estimation (i.e. they seem to be only used separately). I thought it would be great if the sensor drift from the IMU could be fused with somewhat reliable data from the thermopiles. Am I looking at it wrongly or is there a reason why this isn't commonly implemented?
Cheers
Joe

There are two type of IMU.One is thermopiles that it can use easy.But accuracy is alittle low.IMU is the best,But it is very difficut to write own program and build CKT.We use X-sene IMU http://www.xsens.com/en/general/mti-g.But we suggest ,you should use V2 deve:.After that change one.Good luck.

A thermopile cant't work well in many situations, for example close to trees, buildings, or inside clouds. Correcting (overriding) the IMU upon the thermopile doesn't seem reasonable.
