KVH DSP-1760 Fiber Optic Gyro
The DSP-1760 Fiber Optic Gyro from KVH includes KVH's breakthrough photonic integrated chip (PIC) technology for improved reliability and repeatability. This gyro offers versatility with 1,2 or 3 axes of the world's smallest precision FOGs. The DSP-1760 is ideal for commercial applications, including stabilization for land, sea and aerial systems, and navigation of autonomous systems.
Description
Overview
KVH’s DSP-1760 Fiber Optic Gyros (FOGs) combine single- or multi-axes of the world’s smallest high performance FOGs within easy-to-integrate housings, or unhoused for OEM configurations. The DSP-1760 FOG offers exceptional performance in bias stability, scale factor, and angle random walk, and is available in nine configurations to solve the most challenging design projects.
The DSP-1760 FOG is ideal for air, land, or maritime stabilization and pointing applications. Due to its versatility, and accurate, reliable output, it can also be utilized in navigation, guidance, and control systems.
The DSP-1760 FOG is a high bandwidth, extremely low noise sensor. It offers customers a choice of two interfaces: a Micro-D or a circular connector. In addition, the DSP-1760 FOG integrates magnetic shielding within the gyro housing, providing improved performance in systems with problematic magnetic environments.
A key element of the DSP-1760 is KVH’s new, groundbreaking integrated planar optical chip. Replacing individual fiber optic components, the DSP-1760 with PIC Inside™ offer improved reliability, unit-to-unit repeatability, and easier integration. The result is a precision photonic fiber optic gyro sensor that is more durable, reliable, and designed for a high level of repeatability.
All variants offer ease of use and high adaptability, featuring flexible communication options allowing for user-programmable data output rates up to 5000 Hz. The OEM packaged version enable ease of integration into even the smallest of systems.
