im here trying to make my own autopilot using an AVR atmega16..shhh its slow cuz many ppl out there r using least 32mhz... but as a beginner i really cant afford anythin else...i hav am collecting the stuff but i was wondering....the IMU i hav spills out all readings including temperatures....what r these temp. for?...do i need them to make the autopilot....and if any1 has any suggestions regarding a KALMAN FILTER...cuz i am going to apply a kalmafilter to each and evry reading 1 by 1...suggestions r requested....
i have written a code in BASCOM for working out the headings of a pni's magnetometer...i was wondering if i could rely only on the gps for altitude measurement...is it fine for me as a beginner cuz i really hav no real hands on experience on pressure meters or else....throw some light ppl...

Yes, actually you have a chart in the data sheet of the gyro (constant rate vs temp)... Yes for example when the component is cool (like 21 degrees) is going to give a measurement, but in fly the temp will increase (as normal), for ex 40 degrees, a than gyro will give you different readings, so you need to compensate it... Some gyros are already temp compensate and have a build in thermometer.
so like...this change i.e. temp can simply be subtracted or added to get a true reading or is it just an idea of how much the IMU has deceived ?...how do u use temp?...
