Techniques for Improving Resolution in Tilt and Inertial
Resolution is generally limited by noise
 

Given a 500ug/Rt Hz Accelerometer, what is the resolution vs. bandwidth trade-off?
BW(Hz) RMS Noise P-P Estimate (4x) Degree of Uncertainty
1Hz 0.5mg 2.0mg 0.1 degree
10Hz 1.6mg 6.3mg 0.4 degree
100Hz 5.0mg 20mg 1.2 degree
 

Use a peak to peak estimation; measurement is absolute

Be sure to account for an additional filtering due to averaging.
Example: 100hz averaged to 1hz will give 1 Hz noise
