Kearfott offers a variety of IMUs addressing Size, Weight, and Power (SWaP) while meeting the demanding performance needs required by today’s applications such as missiles & munitions operating within GPS denied environments. Consisting of a Monolithic Ring Laser Gyro (MRLG) and three MOD VIIA accelerometers, the IMU provides linear accelerations and angular rates for inertial measurement or autopilot purposes as well as local (body) delta angle and delta velocity information for inertial navigational capability. The strap-down system provides interconnection for power, discretes, and message I/O. IMU communication is configurable to meet application needs. External shock and vibration isolators provide mechanical support and interface with the mounting structure. Isolators and the mounting structure are configurable for application-specific vibration, shock, dynamic response, and bandwidth requirements providing significant mechanical design flexibility at the application level. If desired, Kearfott offers IMUs pre-packaged in custom chassis housings, reducing or eliminating the need for specific procedures or tools associated with mounting sensitive instruments requiring isolation.

Kearfott offers closed loop fiber optic gyros (FOGs) for use in a multitude of applications. FOGs deliver fully-compensated angular rates or angular increments over a serial or analog interface, while providing very long system life and no acoustic noise. Kearfott’s design and manufacture of Fiber Optic Gyro (FOG) inertial sensors relies on proprietary innovations and in-house manufacturing capabilities. Kearfott ensures total control of standards and performance, and delivers exceptional flexibility for tailored requirements.
