Superior FOG Performance, Affordable Prices
The 1725 IMU from KVH 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. The 1725 IMU joins KVH’s array
of advanced inertial sensors designed to meet the demanding needs of a
wide range of navigation and stabilization applications. Like KVH’s highly
successful 1750 IMU, the 1725 IMU leverages the technology of three
DSP-1750 FOGs, the world’s smallest high-performance FOG, integrated
with three low-noise MEMS accelerometers. 


This 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.
Compact Package Designed for Easy Integration


The 1725 IMU weighs less than .7 kg (under 1.45 lbs.) and is a compact
package designed for easy integration in higher-level systems. The flexible
interfaces and programmable message outputs, baud and data rates
make the 1725 IMU highly versatile so as to address the needs of a broad
range of demanding applications such as inertial navigation systems for
unmanned platforms, precision stabilization systems for radar and optical
systems, precision pointing and stabilization systems for antennas and
weapons platforms, as well as high-accuracy mobile mapping systems.
No Compromise Between High Performance and Low Price


The 1725 IMU is highly adaptable, featuring RS-422 asynchronous
communication with user programmable data output rates from 1 to 1000
Hz. With its high bandwidth and low noise, the 1725 IMU can provide the
data output required for challenging applications, and still help keep
program costs low. KVH’s 1725 IMU makes the traditional tradeoff between
performance and price obsolete. Get both FOG-quality performance and
affordability with the KVH 1725 IMU.
