Active Radar Seeker (ARS) provides accurate and stable velocity information, thus possesses the possibility of gimbaled inertial navigation system (GINS) aiding.

It is an effective way in integrated navigation by using Strapdown Inertial navigation System (SINS), GPS and Doppler Velocity Log (DVL).
