Sparton Digital Compass Products

Sparton digital compasses provide affordable superior performance. Sparton's three-axis, tilt-compensated digital compass products provide three-dimensional absolute magnetic field measurement and full 360 degree tilt compensated bearing, pitch, and roll. Our proprietary adaptive algorithms allow our unique, precise sensors to provide continuous and exceptional accuracy in the presence of stray magnetic fields while automatically maintaining heading accuracy under motion conditions.

In addition to improved 3-D calibration, our latest digital compass, the SP3004D, includes a revolutionary 2-D calibration algorithm to optimize performance and allow fast, accurate, in-field, on-equipment calibration for platform based applications. Further enhancements such as selectable baud rates (up to 115,200 Baud) and dynamic filter settings are now included.

Automatic heading stabilization employed under motion conditions enables platforms or vehicles to maintain heading accuracy. Further, our digital compasses correct for declination enabling true heading to be provided. Sparton digital compasses can be integrated into any system using a UART or SPI interface.

Sparton digital compasses are delivered as encapsulated modules ready to meet the requirements of your design application and environment. Sparton also offers product integration, DFM, DFA and production services.

IMPORTANT NOTE: It is important to note that operating environments can adversely affect magnetic compasses. Any device operating in the vicinity of a magnetic compass that produce a time-varying magnetic field may degrade compass performance. In addition, any magnetic material that causes severe magnetic distortions in the vicinity of the compass may also degrade compass performance. It is recommended that Sparton be included at the front-end of your product design to assist with compass integration.
