how to get position and angle in ADIS16488A IMU Sensor

Hi all, I am using  ADIS16488A IMU sensor for finding position and angles in my application. Actually in data sheet, they have mentioned Delta velocity and Delta angle will give one integration of accelerometer and gyroscope output.

So is that enough to integrate one time of delta velocity and delta angle to get position and angles.??? or delta velocity and delta angle gives rate of change of velocity and rate of change of angle???

Or have to double integrate the accelerometer and angular rates to get position and angles.??

    Thank you for your use of the ADIS16488A in your application. To be honest, I am not sure that I understand what you are asking for.  The math associated with converting acceleration information into tracking information is as you offer, a double integration.  Developing sensor fusion routines for managing the influence of gravity, specific sensor behaviors and application-specific conditions is a hot area of research right now.  Many applications value some level of GPS-denied position tracking, but are finding that they need to study both sensor-level behaviors and application-specific motion profiles to develop routines that give them the best service available.   Here is a nice starter reference on this topic:

    What type of application are you working on?
