Overview
The new KVH P-1725 IMU is a compact, commercial IMU featuring breakthrough PIC technology for increased reliability, and upgraded high-performance 10g accelerometers for outstanding FOG performance at MEMS prices. An advanced inertial sensor, the P-1725 IMU is designed to meet the demanding needs of a wide range of navigation and stabilization applications.
Leveraging KVH’s revolutionary PIC technology, the P-1725 includes three photonic FOGs integrated with three high-performance, low-noise 10g accelerometers. The resulting low-cost/high-performance IMU is ideal for manned and unmanned platforms, as well as navigation or stabilization systems where low cost, high performance, and high bandwidth are critical for success.
KVH’s new PIC technology reinvents FOG technology with improved reliability, unit-to-unit repeatability, and easier integration with an integrated planar optical chip that replaces individual fiber optic components. The result is a precision photonic fiber optic gyro sensor that is more durable and reliable with increased performance designed for a high level of repeatability.
With its high bandwidth and low noise, the P-1725 IMU can provide the data output required for challenging applications such as autonomous navigation systems, precision pointing and stabilization systems, as well as mobile mapping systems and still help keep program costs low. KVH’s P-1725 IMU makes the traditional trade-off between performance and price obsolete.
Get both advanced photonic FOG-based quality performance and affordability with the KVH P-1725 IMU. The compact P-1725 is designed for easy integration into new or existing systems.
