Static and Dynamic accuracy of ADIS16480

In the datasheet of ADIS16480, it is mentioned that Static and Dynamic accuracy of angle outputs depends on " 1 Accuracy specifications assume calibration of accelerometers and magnetometers to address sensor drift and local influences on magnetic fields. ".  What are the calibration and assumptions considered to achieve this accuracy ? Will i get the mentioned accuracy if the module is switched on on a moving platform ? Can i use the same for applications underwater (inside a tow fish) ?
