DSP-4000 Fiber Optic Gyro

Product Images: Previous ImageNext Image

The KVH DSP-4000 FOG is a high-performance, low-cost successor to troublesome mechanical gyros for commercial and military applications. The all-fiber design ensures high reliability, superior performance, and exceptional vibration, shock, and acceleration survivability. The dual-axis DSP-4000 also features low noise, high bandwidth, improved bias stability, and excellent resolution, making it an affordable solution that delivers superior stabilization and tracking capabilities for turret, antenna, and optical stabilization systems.

Designed to meet required rigorous military specifications, the DSP-4000 offers military and commercial customers a scalable solution, enabling deployment of next generation gun and turret stabilization designs, as well as dynamic pointing capabilities within a minimal form factor. Originally designed as a replacement for mechanical gyros that were once the only option, the DSP-4000 has evolved into a flexible system for stabilization, navigation, and targeting applications.

The DSP 4000 is controlled by the Arms Export Control Act (Title 22, USC Sec 2751 et seq.) and the International Traffic in Arms Regulations, ITAR, 22 CFR 120-130, and may not be exported from the United States or disclosed to a foreign person in the united States except as authorized by those regulations.
