E-compass for cell-phone

With the ever-changing technology, the consumer market of smart phones has also added the function of an e-compass, which can be used with GPS for navigation and azimuth identification. Although GPS is widely used in navigation and positioning, but in fact, GPS signals are often blocked by terrain or buildings and their accuracy is greatly reduced. Especially in a city with many high-rise buildings or a mountainous area with dense trees, and if it is stationary, GPS cannot accurately determine the direction information. And then the e-compass can provide effective and immediate assistance. When the cell-phone detects that the GPS cannot be positioned, the e-compass can be used to determine the orientation, and the acceleration sensor and gyroscope can be used to determine the movement speed and orientation, and then "calculate" the current position.

Based on our small package size, our product can be used in mobile communication device to orient the absolute direction, detect motion status and game console. So that make immediate adjustments to the current moving direction at any time, to avoid deviation from the correct heading due to confusion in the direction. It can also be used on the controller of the game console to detect motion status and game console at any time. Whether it is GPS navigation directions or the games by cell-phone that need to be determined by location, the e-compass with high accuracy and low noise can enable end consumers to have a better experience in the using of cell-phones. We provide small size magnetic sensing IC with high accuracy, low power consumption and low noise. For different applications, we can provide customers with complete engineering support and solutions.
