A:

Strong magnetic fields have the ability to cause apparent drift in the gyro bias. This is due to the Faraday effect on the laser light in the sensing coil resulting in non-reciprocal light paths. While this effect can be observed in gyros designed for precision inertial navigation systems (drift rates of less than 1 degree per hour), and can be mitigated by the use of mu-metal shielding, there have been no reported problems with KVH FOGs. If your application results in mounting a FOG near a very strong magnetic field (>50 gauss), a practical test to determine sensitivity is suggested.

A:
Yes, the TG-6000 is ideally suited for GPS-integrated navigation and motion control.
A:

All KVH FOG products meet the European Community Electromagnetic Compatibility Directive and are approved to display the CE mark. They have been tested for conformance to electromagnetic emissions and susceptibility requirements. The units also meet FCC Part 15.

A:

Yes. Complete product details are available on the TG-6000 product page.

A:

Some of the many applications for the Tactical Grade Inertial Measurement Unit are: avionics, antenna and optics stabilization, UAV/ROV guidance, flight controls, GPS augmentation, marine motion sensing, navigation, and autonomous vehicles.

A:
The TG-6000 has a gyro bias accuracy of 1 degree per hour, 1 sigma at a constant temperature and an accelerometer bias accuracy of +10 mg maximum.
A:
The geometrical birefringence created by the elliptical core is the key to the E-Core fiber's outstanding polarization-maintaining abilities. Because of its design, it is able to maintain its polarization and low-loss characteristics when exposed to physical stresses and temperature-induced changes far better than PM fiber created using stress-induced birefringence. It is the E-Core fiber's stability that makes it an excellent choice for pigtailing optical components.
A:
The simplest explanation is that the IMU integrates 3 axes of fiber optic gyros with 3 axes of accelerometers in one package. All KVH fiber optic gyros combine KVH's proprietary polarization-maintaining optical fiber and fiber components with integrated digital signal processing. The result is a highly reliable system with no moving parts to wear out or require maintenance. These gyros provide extremely precise rotational rate information by measuring the phase difference between two paths of light traveling in opposite directions through an optical fiber. This rate information is then processed in a digital data stream to a variety of external systems.

KVH offers several integrated systems with IMU functionality, including the TG-6000, CNS-5000, and CG-5100.
A:
Yes, the TG-6000 Tactical Grade Inertial Measurement Unit is a high-performance, 6 degree-of-freedom, fiber optic gyro-based motion sensing package suited for many military applications, including avionics, antenna and optics stabilization, UAV/ROV guidance, flight controls, GPS augmentation, marine motion sensing, navigation, and autonomous vehicles.
