Sensor fusion enables e-compass

Sensor fusion enables electronic compass applications via @EE_Times

PORTLAND, Ore.—Electronic compass applications combine magnetometer-provided headings with corrections from inertial sensors that compensate for stray magnetic fields. As a result, sensor fusion algorithms provide fast, reliable electronic compass—or e-compass—readings for context-awareness applications like mobile location-based services, 3-D games and e-health. For users of Freescale Semiconductor's magnetometers and accelerometers, e-compass sensor fusion algorithms are now available as a free download. "Our sensor fusion algorithms use the strengths of one sensor to overcome the weakness of the other, resulting in fast, accurate and reliable readings," said Michelle Kelsey, Freescale's product-line manager for sensors in mobile markets. "Freescale's Xtrinsic e-compass software enables applications in augmented reality, e-health, gaming and navigation." Freescale is off...
