GPS performance comparison of various Windows Mobile phones published March 23, 2008 [Pocket PC phone] | By Edward J. R. Nowadays having built-in GPS is not enough: users want to have built-in GPS that is very sensitive so that one can get GPS-location-fix quickly and also tracking of the location while moving should be accurate. When it comes to built-in GPS in mobile phones, the GPS performance depends on 2 factors: the chipset used and size of the antenna. Furthermore one can get faster GPS fix with use of software that is downloading supportive GPS data from Internet (so called "assisted GPS") but still it looks like the chipset and antenna are 2 deciding factors. Here 3 Windows Mobile phones with 3 most popular chipsets are being compared... .. namely HTC TyTn II, Samsung i780 and E-TEN X600: To overcome the reduced signal fed to the chips by the diminutive GPS antennas, all these PDAPhones have some form of A-GPS, "Ephemeris AGPS" for the X600 with SiRFInstantFixI and the HTC TyTn II with gpsOneXtra, and MS-Based for the Nokia N95 (supl Nokia) and the Samsung i780 (supl Orange). As a result, warm TTFF is obtained in less than ten seconds. For the purposes of this comparison, all the systems were left to "settle" for 10 minutes in the open to remove the impact of these various forms of AGPS To learn more, read GPS-sensitivity comparison of various Windows Mobile phones.
