Continuing in its tradition of improving the accuracy of portable navigation devices while completely butchering the capitalization rules that we all hold so dear, San Jose-based SiRF Technology Holdings Inc. has announced a new, um, technology called SiRFDiRect that promises to offer the same low-signal prowess in your nuvi
that's normally found in those overpriced in-dash units pushed by car salesmen. Using a combination of fancy-schmancy algorithms and so-called "dead reckoning" hardware sensors (Dead Reckoning, DiRect, get it?), properly-equipped products will be able to maintain a course even in the complete absence of a signal by using heading and acceleration data to fill in the blanks -- perfect for traveling under dense forest canopies or through the dreaded urban canyon (pictured). Engadget-regular Mio
will be the first manufacturer to incorporate this new tech -- branded "Navisteadi" -- in its wares, with other models that use the GSC3e/LP and GSC3f/LP chip sets set to get their reckonin' on in the third quarter.
