ST produces chip-set for linear, angular and magnetic sensing

ST has put together a three sensor chip-set comprising a geo-magnetic module, a gyroscope, and a pressure sensor to provide  linear, angular and magnetic motion sensing for better navigation and a smarter user interface in mobile devices.

The three MEMS devices  are aimed at location-based services and pedestrian dead-reckoning for indoor and multi-floor navigation, requiring rather complex sensing capabilities.

By using the three MEMS sensors  a consumer device can have a complete indication of its linear acceleration, angular velocity, earth gravity, heading and altitude.

With this information, mobile users will be able to identify their direction and precise location in all three dimensions everywhere they go, including in places with no or low GPS signal, such as inside buildings in urban canyons or in mountainous and forested terrain.
