GPS and GSM Are Getting Incorporated

by diane 2010-03-06 06:19

Today GPS is getting incorporated in GSMs(Europe), cell phones(USA) and mobile phones(UK) and this development is accelerating in a great pace. In only a couple of years (almost) all GSMs will have a GPS receiver incorporated. And not the poor performing GPS receivers as we know them now from our handheld devices. No, the GSM/GPS combinations must be able to locate themselves under the most difficult circumstances i.e. indoors, in parking garages, in urban canyons, in large buildings etc.
The market for these GPS receivers is so huge, compared to the market for handheld GPS receivers (a factor 200 or so), that every manufacturer will put all on all to make this a success.
We already knew the Global Locate A-GPS chip-set with over 20,000 hardware correlators integrated. This means that the hardware does a lot of the computational work. Acquires satellites with signals below -158dBm at a 100 times lower power consumption. Time-to-first-fix as low as 250 msec. In the mean time Global Locate has been taken over by Broadcom.
And SiRF sells its third generation SiRFStarIII chipset with the equivalent of more than 200,000 correlators. Weak GPS signals (up to -159dBm) can be processed and with that indoor GPS exists already. The SiRFSoft GPS architecture is portable to the market leading platforms such as Intel XScale and OMAPI. This means that the system can be incorporated in GSMs, cell phones, Smartphones, PDAs and other wireless handheld devices.
Hundreds of millions of people will permanently carry a high performance GPS receiver with them, wherever they go. GPS and GSM go together.
