Hi. Im designing( well, trying to) design a # D tracking system using MEMS accelerometers and gyros. As there are so many errors associated with MEMS devices and the dead reckoning algorithm. I need some help on the errors in MEMS. I have identified the following errors:
1. Zero g bias error-----If the temp. is constant can I overcome it??
2. Drift error-----Is this due to noise??? If so can it be removed using Kalman filter. If not, then what is the alternative?
3. Also as I am using many sensors, Im having axis misalignment errors. Can it be overcome??
4. Also due to integration to find position, we have errors. Is this the same as drift error???
Kindly help me.
Thank You
Ashwin.
