I would like to accurately determine an absolute travel distance (forward and reverse) from a starting point using a 3-axis accelerometer (less than 1 km total linear distance). I have tried web searches and can find lots of devices and descriptions on how the devices work but very little on the actual algorithms. I know how to use vectors to calculate a distance from the x & y axis as well as calculating velocity from acceleration, but I can find nothing that describes how to correct for tilt.
Is there a resource somewhere where I can read up on this?
Note that I am not interested in GPS; I would like something more accurate without having to hassle with DGPS.
