概要

論文の詳細を見る
The world's smallest electronic compass for mobile phone applications was recently developed by Aichi Steel Corporation. The compass has two orthogonally arranged MI sensor elements and a signal conditioning IC. The dimensions are 3.1 × 3.4 × 0.8 mm, which is less than 1/1000 the volume of conventional fluxgate-type electronic compasses. The new electronic compass has high direction resolution, low energy consumption, and fast response. The compass will be used in mobile phones with GPS (global positioning system) capability for pedestrian navigation services, which give direction and location related information by accessing a database via the Internet. An electronic compass is indispensable for map-based navigation services, giving a user-friendly 'heading-upward' display by automatically rotating the map according to the user orientation. This service will be launched in the fall of 2003.
