The versatile new KVH CNS-5000 combines two complementary technologies – KVH’s fiber optic gyro-based inertial measurement unit (IMU) with NovAtel’s OEM6® GNSS precision receiver technology – within a single enclosure. The deep coupling of these technologies within the CNS-5000 optimizes the raw GPS and IMU data, delivering a superior position, velocity and attitude solution. Composed entirely of commercial components, the rugged CNS-5000 meets COTS requirements, minimizing the operational complexities for customers whose products cross international boundaries.

In commercial industries like seaport management, surveying, autonomous vehicles, precision agriculture, and guidance operations, it is crucial to know where staff, equipment, and supplies are located at all times and at a moment’s notice. Through its seamless integration of these two highly reliable navigation systems, the CNS-5000 provides the perfect solution to these needs in a groundbreaking low-cost, small form factor solution designed for 3-D positioning, velocity, and attitude measurement.

FAQ

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:
KVH's E-Core fiber offers a number of advantages, including high polarization maintaining ability (greater than 40 dB-m) and low sensitivity to stress and temperature. These features make E-Core fiber ideal for fiber splicing and pigtailing to other optical components in applications where preserving the state of light polarization is critical to the operation of the device.

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.

The elliptically shaped core region within an E-Core fiber has a significantly higher index than the surrounding cladding, creating the geometrical birefringence necessary to maintain the polarization of the light within the fiber. The E-Core fibers are manufactured using high-grade silica materials and various high-purity dopants. A dual UV-cured acrylate coating is applied to standard fibers, thereby preventing moisture from penetrating the fiber, preserving its strength, and improving its handling characteristics.

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:
Please see the installation and technical manual for your KVH FOG-based product for complete details of any specific power requirements.
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.
