In 2009 we learned that Apple began researching new sophisticated in-vehicle navigation systems. Then in 2011 we further learned that they were working on ways to advance their "Maps + Compass" iOS application with augmented reality. And before 2011 closed out, Apple acquired C3 Technologies which is likely to bring photo-realistic mapping to iOS devices in the not-too-distant future. Adding to this momentum we learn today that Apple has invented an advanced magnetometer application and related system. It's designed specifically to provide iOS devices with greater mapping and navigation accuracy. And to be absolutely clear about their market focus, Apple specifically lists navigation systems for vehicles, aircraft and watercraft.
