Overview
EMCORE’s DSP-1760 FOG combines single-axis or multi-axes of the world’s smallest high performance fiber optic gyroscope 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.
Available in single- or multi-axis gyro configurations, the DSP-1760 FOG is a high bandwidth, extremely low noise sensor. The DSP-1760 FOG 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 FOG is EMCORE’s new, groundbreaking integrated planar optical chip. Replacing individual fiber optic components, the DSP-1760 FOG 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.
The DSP-1760 FOG provides unmatched versatility to meet the demands of the most challenging design projects. Choose a 1-axis, 2-axis, or 3-axis configuration, each employing the world’s smallest precision FOG, and either the housed design or the unhoused OEM variant. 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.
