i use accelerometer to detect position to.
1. Mr. tom becker : "what do you mean with "Dead Reckoning"?
2. Mr.Sam...I have also used the double integration :
u said that :
V(k)=V(k-1)+A(k)*DT
P(k)=P(k-1)+1/2*A(k)*DT*DT

i have the same one for V(k), but for the P(k)=P(k-1)+V(k)*DT. Is it the same??
3. i dont know why the voltage output in passive condition (not moving), is always change/unstable??is it noise?? do i have to add filter??

4. when i try it, to measure the distance...sometime it gives different results...with fast/medium/low acceleration..whereas it should be the same distance...however the acceleration.
thanks
