Abstract
An inertial sensor system according to one embodiment having a platform with an x axis and a y axis, a rotational table that is free to rotate about the x axis, a rotational table gyroscope mounted onto the rotational table to measure p, q, and r rotation rates referenced to the rotational table and at least one platform gyroscope mounted off the rotational table, wherein the rotational table gyroscope and the platform gyroscope provide sense rotation used to process gyroscope biases that are used to correct measurements for the inertial sensing system.
