new SiRFDirect uses heading and acceleration sensors
Jun 6, 2007 gps navigation, mio, misc news
GPS manufacturer SiRF today announced a new technology they call “SiRFDirect” which enables GPS navigation manufacturers to provide tracking and accuracy capabilities so far only available in higher-end systems.
SiRFDiRect technology uses heading and acceleration data from the sensors to boost the accuracy of portable navigation systems when GPS signals are weak or blocked, such as in dense urban canyons and tunnels. Transitions between combined GPS/DR and dead-reckoning-only operation are seamless and accurate without operator intervention, and the closely coupled GPS/DR architecture of SiRFDiRect technology continuously auto-calibrates the heading and acceleration sensors…
The first adapter of SiRF’s new SiRFDirect technology will be Mio which is expected to reveal a few new models at Computex Taipei 2007. Mio will call this technology Navsteadi.
