Fibre-optic Gyro IMUs for Demanding Applications
KVH Industries, USA, has introduced the 1725 inertial measurement unit (IMU) and the 1775 IMU, advanced sensors designed to be integrated into the most demanding stabilisation, pointing and navigation applications. These two products complement KVH’s 1750 IMU and create a complete range of choices for 6-degrees-of-freedom (DOF) sensors. All three products utilise the E•Core ThinFiber technology of KVH’s DSP-1750 fiber-optic gyro (FOG).
The 1725 IMU features a flexible user interface, with user programmable data output rates from 1 to 1000Hz. It delivers excellent FOG performance and stability at a price comparable to competitive MEMS-based IMUs. The 1725 IMU is suited for all platforms and navigation or stabilisation systems where low cost, high-performance, and high bandwidth are critical for success.
The 1775 IMU is a premium sensor designed to deliver the highest level of performance to meet the demands of platforms requiring superior performance in the most challenging environments. Providing ease of integration for designers of high-level inertial navigation, guidance, or stabilisation systems, the 1775 IMU offers a flexible interface with user-programmable data output rates from 1 to 5,000Hz. It includes 3 axes of magnetometers for automatic gyro bias compensation even in the presence of strong magnetic fields. The 1775 IMU is designed for sophisticated systems and applications where very high bandwidth, low latency, and extreme stability are critical.
Like KVH’s 1750 IMU, which was introduced in 2012, the 1725 IMU and the 1775 IMU incorporate 3 axes of KVH’s DSP-1750 FOG, the world’s smallest high-performance FOG, integrated with 3 axes of advanced accelerometer technology. All three IMUs provide excellent shock, vibration, and thermal performance, as well as a compact form factor.
These three products facilitate system designers and integrators with a high-performance solution for every application – ranging from manned and unmanned commercial and defence platforms, optical equipment stabilisation systems, and pipeline inspection equipment, to autonomous vehicle control and navigation. This line satisfies the performance, size, and price parameters for IMUs due to KVH’s control over the design and manufacturing process, from creating the fibre to integrating all of the IMU components into the final design. Maintaining complete control of this process, combined with our proprietary technologies, allows KVH to offer a combination of innovative solutions, quality, and affordable options for nearly every stabilisation or guidance application, according to the supplier.
