imu position and sampling rate
Posted: Wed Apr 07, 2010 4:12 pm
hi guys im still new to these sensors..
couldn't really find the basics on the internet...wanted to ask you how does position of accelerometer/gyroscope/combined on your system affect sensing capability? i just can't vsualize it. for example if you place them in the middle of your system or at the edge. what difference will there be? will angles still be accurate?
secondly, how does ADC sampling rate affect your data, pitch and roll? how do you decide a rate to obtain angles correctly?
does nyquist rate and aliasing matter?
thankssss
