AKM Electronic Compass Technology


What makes AKM different ?

Ultra-compact package

Asahi Kasei Microdevices Corporation (AKM) is a manufacturer of 3-axis electronic compasses that use the Hall element technology. Since 2003, we have been offering 3-axis electronic compasses for consumer use, making substantial contributions to the popularization of electronic compasses.

AKM electronic compass uses magnetic sensors (Hall element) with wide dynamic range and ideal linearity. The silicon monolithic structure achieves high accuracy and reliability, and it is optimized for high-volume manufacturing. Based on this technology, AKM's electronic compass can detect azimuth direction with a very high accuracy. In addition, with small and thin packaging, AKM’s electronic compass is widely used in products with limited mounting space, such as Smartphones. 
AKM, with its extensive knowledge of electronic compass, is the ideal partner if you are considering to implement a “pedestrian navigation with GPS” on a cell phone, mobile tablet or mobile PC. 

We provide not only hardware, but also DOE™ compensation software (winning "the Imperial Invention Award of the Japan Institute of Invention and Innovation" FY 2012), in addition to other software applications that enhance the user experience with our electronic compass.
The combination of hardware, software and technical support is an advantageous characteristic of the AKM electronic compass.

We will continue to provide the best solution through development of the compact, low-voltage and high-performance electronic compass and advanced software to our customers in the future.
