Abstract
A system and method for using a survey tool within a borehole is provided. The survey tool includes a plurality of rotation sensors each having a sensing axis and a direction of least acceleration sensitivity. The sensing axes of the plurality of rotation sensors are generally parallel to one another and the directions of least acceleration sensitivity of the plurality of rotation sensors are generally non-parallel to one another.
