<p>A method and system for estimation of inertial sensor errors is provided. The method includes receiving first inertial output data from a master inertial measurement unit (IMU) mounted on a host platform, with the first inertial output data comprising a change in velocity (delta V) and a change in angle (delta theta), and receiving second inertial output data from a remote IMU mounted on the host platform at a predetermined fixed distance from the master IMU, with the second inertial output data comprising a delta V and a delta theta. The first inertial output data is compared with the second inertial output data to determine a difference between the delta V of the first inertial output data and the delta V of the second inertial output data, and to determine a difference between the delta theta of the first inertial output data and the delta theta of the second inertial output data. The determined differences are applied to estimate inertial sensor errors in the remote IMU.
