1725 IMU

Fiber Optic Gyro IMU Delivering Superior Performance at MEMS Prices

The 1725 IMU is a game-changing 6-degrees-of-freedom (6-DOF) sensor that delivers the high performance and stability of KVH’s fiber optic gyros (FOGs) at MEMS prices. With three high-performance KVH gyros and three low-noise MEMS accelerometers, this commercial-off-the-shelf, low cost/high performance IMU is ideal for applications in which affordability, high performance and high bandwidth are critical. Features:

  • Compact package weighing less than 0.7 kg (1.45 lbs.) designed for ease of integration
  • Flexible interfaces, programmable message outputs
  • Versatile for unmanned platforms, precision stabilization systems, and high accuracy mobile mapping

Technology Details

Exclusive Technology

E•Core ThinFiber Technology

KVH’s proprietary polarization maintaining E•Core ThinFiber delivers outstanding precision performance in much smaller gyros and inertial systems. By minimizing the diameter of KVH’s standard E•Core fiber, the resulting ThinFiber boosts the accuracy of all KVH gyros, and allows the production of very small FOGs with very high bandwidth and very low noise.

DSP Technology

KVH’s DSP electronics improve FOG performance in critical areas such as scale factor and bias vs. temperature, scale factor linearity, and maximum input rate. KVH’s exclusive DSP design overcomes the limitations of analog signal processing, eliminating temperature-sensitive drift and rotation errors.
