Calibration line is AC coupled to the preamplifier input, with 6 dB attenuation. It can be used to test electrical system integrity. An electrical input signal is applied to the cal line (blue) at cable termination. The output signal level is then measured. The output level will be 6 dB less than the input level. Note: the maximum calibration input level = 16 volts peak to peak, 5.7 volts RMS. The calibration line can also be grounded to minimize noise during use, if necessary.
Shield connections are floating (not grounded) at the preamp; they can be grounded at the cable end to minimize noise, if necessary.

Inertial Sensor Systems
Yes. Sparton sensors have been specifically designed for both commercial and high-reliability applications. The materials and chemicals used in the design, assembly, and manufacture of our products do not exceed the thresholds set forth in the RoHS Directive 2002/95/EC for Lead, Cadmium, Mercury, Hexavalent Chromium, Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE).
The Sparton NorthTek™ application platform is a powerful, next-generation feature that positions the DC-4 and GEDC-6 inertial systems as the world’s only fully programmable sensor, allowing virtually limitless customizations and applications. NorthTek™ is based upon the Forth programming language, and allows the ability to tailor a NorthTek™ equipped sensor to the operating environment of a product.
Sparton AdaptNav™ sensor fusion adaptive algorithms provide real-time (non-linear) sensor heading optimizations when used in varying magnetic and dynamic operating environments, offering unparalleled orientation accuracy under the most challenging conditions. AdaptNav™ algorithms look at the system dynamics of the sensor environment in real-time and make adjustments based on optimal sensor reliability modeling. AdaptNav™ improves on current Kalman filter based approaches (including extended Kalman filters) by not requiring a dynamic profile to be preselected. There is no need to pre-select option models or use ‘trial and error’ parameter settings prior to deployment in the sensor application, which eliminates the guesswork often associated with many Kalman filter implementations.
Yes. In fact, Sparton inertial systems provide both Magnetic and True North indicators.
Sparton sensors will accept inputs of latitude, longitude, date, and altitude information and calculate the magnetic variation based on your position. They will then use the magnetic variation to provide a True North output.
All sensors will experience performance degradation with latitude. At the North/South magnetic poles, the magnetic field is vertical and gives no indication of direction. Therefore, compasses will be more accurate at the equator than the poles.
The X, Y and Z axes are relative to the sensor board. Refer to the Sparton Sensor Product Guide and the NDS-1 Navigation Development System Users Guide for more information.
Sparton sensors are designed such so they can support any mounting orientation. This is a User-Selectable feature. The sensor will indicate the heading that corresponds to the angle between Magnetic North and the North direction of the compass board. Refer to the Sparton sensors Product Guide for more information.
Pitch is associated with rotation about the Y-axis. It is measured using the X-axis accelerometer to measure Tilt. Similarly, Roll is associated with rotation about the X-axis and is measured using the Y-axis accelerometer. Refer to the Sparton sensor Product Guide for more information.
