No, you wouldn't use both. They do the same thing, via different methods. At the moment, the IMU is a stand-alone product and is not intended to work with ArduPilot.

Is it possible I wonder to use each with a separate ardu and process the data with another larger more powerful processor? Like for instance HUD, IMU/(magnetometer,accelerometer,gyro), Thermophile, and use the ardu as a subsystem?

Sure. But why? What does the Thermopile give you that the IMU does not?

Well, bud? You cant use GPS to land on the moon! :) We joined forces with the open source GLXP (google lunar x-prize) Team Frednet! and are prototyping a real lunar lander. Mark I may use Ardu hardware!

how so? GPS isn't even mentioned in this post.

Well, For our use we take for granted that the IMU uses the GPS data for positioning. It is true you dont have to use it.

Progress is being made we have a kilman filter and are wittling it down to less than 100ms

Wishes do come true! So be careful what you wish for! (You might get it!)
Hopefully my guy's and I can help everybody out here and get the ardu to do some really interesting things! (Like it doesn't already?) It helps if you actually do something of course!

I have had my eye on ya'll for a while now. Now we are about to implement one of these systems and I like the Ardu!

I like the Ardu too, but seriously, for a lunar lander???

Also, GPS only corrects the yaw in ArduIMU. You get no yaw information from the thermopiles, so actually no GPS is not a good reason to use thermopiles in conjunction with ArduIMU. There may be other good reasons however.
