An alignment system for sensor or other electrical device filters rate data from gyroscopes and integrates the same to determine an alignment error state that is populated into a direction cosine matrix that pre-rotates measurement from a first electrical device into an estimated coordinate frame to determine a static alignment between first and second electrical devices or sensors. The system may be part of a countermeasure system on an aircraft. A first electrical device may be an inertial navigation system (INS), and a second electrical device may be an inertial measurement unit (IMU). The attitude of the IMU is used to translate the detected threats from the countermeasure system into a common reference frame of the INS.
