;)

I think I may actually get a receiver with one of these chipsets in when they come to market, my old SirfSTAR III-based receiver doesn't always cut it in urban areas for accurate log-taking (and now I've started doing OSM stuff (streetmapping) it's sometimes not accurate at all).

Here's hoping that the new chipset devices come to market soon :)]]>Feb 9th 2008 9:28PMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/Feb 9th 2008 10:26PMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/Feb 9th 2008 10:59PMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/Feb 9th 2008 11:40PMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/mobile phones have been having co-processors for a while now that speed up the graphics capabilities and therefore make the scrolling and refresh rate of the navigation software a pleasant experience.
now with this new GPS chip, it incorporates such graphics acceleration that otherwise wouldn't be possible, because navigation units DON'T use mobile phone chips.
i only hope that there will be a version WITHOUT 3d acceleration so that it can be included as a module in mobile phones. would be madness to include the 3d part and have duplicate hardware n a single device.]]>Feb 9th 2008 11:46PMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/Feb 10th 2008 12:42AMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/
SiRF just introduced SiRFprima, a new super sensitive GPS receiver platform combined with hardware-accelerated 3D graphics and multimedia encoding and decoding engines designed to significantly enhance user experience for location applications and media rich content.]]>Feb 10th 2008 12:45AMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/
GPS works under the presumption that you are within the spheres of radius of detection of 3 satellites and you are ON the Circumference of a of a 4th sphere, that is the earth.

The altitude detection is by some other hax.]]>Feb 10th 2008 2:51AMhttp://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/http://www.engadget.com/2008/02/09/sirfprima-gps-receiver-platform-boosts-sensitivity-adds-3d-acce/
A three satellite fix, as you say, assumes the Earth is a perfect sphere and that the receiver is at zero altitude. Neither of these assumptions is perfect, so three satellite fixes are very inaccurate, compared to four.

Incidentally GPS isn't nearly as accurate for altitude, as it is for lat/lon. Most people I know don't trust it.
