System analysis and design of a low-cost micromechanical seeker system
… target environment. Furthermore, ultra-accurate inertial measurement units (IMU) that serve as stand-alone guidance systems are very expensive and offer no terminal guidance enhancement. As a result, it is cost prohibitive to equip some platforms with precision guidance capability. The demand for …
