The first implementation of SiRFDiRect technology integrates the award-winning SiRFstarIIIŽ architecture with low-cost heading and acceleration sensors to give portable devices continuous and accurate navigation capabilities typically found in very high-end in-car navigation systems."</i><br /><br /><img src="http://www.pocketpcthoughts.com/images/web/2003/sirf_logo.gif" /><br /><br />While I always knew that my in-car navigational system worked much more effectively and seamlessly than my prior portable Garmin Nuvi unit, I didn't realize it was due to I didn't realize it was due to "dead-reckoning sensor" technology. SiRF Technology is now looking to introduce that capability into newer GPS units that will allow any portable to work just like the expensive built-in systems we've come to see in the newer vehicle models. The complete reference designs are reportedly scheduled to be available during the 3rd quarter of this year with the GSC3e/LP and GSC3f/LP chip sets.
