Kearfott's IMUs are ideally suited for those applications requiring high performance in a compact form factor, and at a cost compatible with large volume tactical programs.
Description: Cost, performance and size advantages have been achieved by incorporating the T24 (MRLG) and a MOD VIIA Accelerometer Triad into an Inertial Sensor Assembly (ISA), and developing the associated IMU electronics to fit on a single compact card. The MRLG IMU is available as a separate ISA and an electronics board suitable for integration into specific program application form factors. The IMU electronics may also be incorporated by the user, along with other system unique electronics, onto a combined board to achieve overall system cost and size advantages. This modular approach allows for interchangeability with our Tactical grade ISA where both High and Tactical grade performance is required on an interchangeable basis. 1-Board Electronics1-Board Electronics
