A:
The Bias Offset is the apparent rotation rate when the gyro is not rotating about its sensitive axis (In precision applications, the user should note that the gyro does measure rotation in inertial space, and the gyro may be measuring a component of the Earth's rotation, of up to 15 deg/hr). The E-Core 1000 is a low-cost product, and uses analog components in the signal processing electronics. There are temperature-dependent offsets in some of the circuits, and this results in a deterministic relationship between bias offset and temperature for each gyro. Bias Offset is the long-term mean indicated rate at a constant temperature when the gyro is not rotating.

The gyro has a temperature sensor whose output is available in both the analog and digital versions. In a land navigation application, the bias offset can be estimated by measuring the apparent rotation rate when the vehicle is stationary. This can be subtracted from the gyro output to yield the true rotation rate. The accuracy of the estimate is dependent on the ARW, since the measurement will have a noise component for short times.
A:
The deviation from the best fit straight line through the input rate-indicated rate data. We describe this in percentage of full-scale reading. The attached figure shows the input-output relationship of the gyro, which is desired to be a straight line, and the percentage error as a function of input rate.
A:
This is the constant of proportionality between the actual gyro rotation about its sensitive axis and the gyro indicated output. In our gyro the output is either in volts/degree/sec (analog) or degrees/bit (digital). The digital gyro output can also be interpreted as the average rotation rate in degrees/sec/bit by multiplying the value by a factor of 10.
A:

Also called the sensitive axis, the input axis is a line perpendicular the plane of the fiber coil and the mounting plate of the gyro. A fiber optic gyro is a true single-axis rate sensor and does not respond to rotations in other axial directions; it is thus said to be insensitive to "g" forces. An arrow on the side of the gyro indicates the sense of rotation that yields a positive rate. Inverting the gyro would change the sign of the rate, but note that the arrow still points in the direction of the positive rate.

A:

The temperature specification presumes that the gyro is mounted to a metallic surface that is at no higher temperature than the ambient air. Although a bare metal surfaces is best, a painted surface is acceptable. Surfaces with poor conduction will reduce the upper temperature limit of performance. The indicated reading of the internal temperature sensor should not, under any circumstances, be permitted to exceed 85°C (185°F).

A:
KVH's digital signal processing (DSP) technology represents a breakthrough in open-loop fiber optic gyro design that enables KVH Industries to support a wide range of applications ranging from stabilized weapons to torpedo guidance, drone and unmanned aerial vehicle navigation, land vehicle navigation, and smart munitions guidance. The DSP class of gyros is not only suitable for use in these and a variety of commercial applications but they are also offer significant cost advantages over competing ring laser and closed-loop fiber optic gyros.

The combination of accuracy, versatility, and value make these systems extremely attractive and reliable solutions for the most demanding applications.
