Hi Venki,

There's a link to the data sheet here:

http://www.cvhsrobotics.org/resources.htm

Naviagation with an IMU is really tricky and at best only good for short distances because the positional error is always increasing. I certainly don't mean to dissuade you because you'll learn a lot from doing it. To get you started, a Kalman filter is commonly used to clean-up the output of gyros. If you get really stuck, shoot me an e-mail and I'll get you some help.
