DSP-4000 Fiber Optic Gyro

Product Images:

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.

FAQ

Can the DSP-4000 be combined with GPS?

Yes, all of KVH's FOGs have the capability of being combined with GPS, making integrated GPS/INS, AHRS, and inertial measurement units a reality.

What are the technical specifications for the DSP-4000?

Technical specifications and complete details are available on the DSP-4000 Product Page .

For what applications can the DSP-4000 be used?

Designed and tested to rigorous military standards, the rugged DSP-4000 series meets or exceeds required military specifications and offers the military the next generation of gun and turret stabilization as well as dynamic pointing capabilities. The DSP-4000 is ideal for demanding applications, including platform positioning and stabilized pointing, gun and turret stabilization, and antennas/optical/camera stabilization.

What is the DSP-4000?

The DSP-4000 fiber optic gyro (FOG) is a low-cost, high-performance alternative to mechanical gyros. It offers superior stabilization of both single- and dual-axis configurations specifically designed to provide the military with a successor to troublesome mechanical gyros. For complete product details, please visit the DSP-4000 Product Page.

What technology does the DSP-4000 use?

The DSP-4000 uses an all-fiber design with no moving parts to wear out or fail, ensuring high reliability, superior performance, and exceptional vibration, shock, and acceleration survivability. The DSP-4000 series also features low noise, high bandwidth, improved bias stability, and excellent resolution.

Unlike mechanical gyros, the DSP-4000 series is insensitive to cross-axis motion and inertia and its high bandwidth makes it particularly suitable for armored vehicle gun stabilization.
