comment Position from 3 dimensional acceleration data?
As @DanielLichtblau pointed out, it's not clear what problem you've identified. That said, what you're trying to do is tricky, at best. Since you're doubly integrating accelerometer data, biases become a major error source (the bias is the value that the sensor indicates when it's not accelerating). Furthermore, biases drift, so correcting for them is challenging. Add to that noise and other error sources, and you've got a tough problem. Finally, you need to correct for the rotational motion of the earth...
