Working with GPS hardware is a bit frustrating in general as most of
the companies involved are rather secretive. So unless you have
a BIG budget project it will be quite difficult to find any info.
The only exception to this rule that I know about is Zarlink.
Check the ARM based "GP4020 GPS Baseband Processor" and companion
chips. There is a fair amount of data available on Zarlink website,

Check out the STMicroelectronics STA205x and STA206x (Cartesio) controllers.

Sirf offers a development kit, although I do not know the cost. We
looked at the possibility of doing something similiar on a Sirf Star II
GPS module, but ultimately just didn't have the code space we needed.

Hi All,
I've developed a few GPS logger solutions around the LPCs and it's
frustrating that most GPS modules have an ARM7 core inside already.
The latest u-blox modules have SPI, RS232 and USB ports right off the
GPS module which is everything I need but I still have to bolt on
another LPC to do a little file system stuff and add a few sensors.
Atmel just announced a new micro with on-chip GPS which must be the
first of this type of convergence. It would save on components and
cost if I could run a few snippits on the GPS module ARM7 to provide
the extra functions I need.
Anyone know of a vendor that gives access to the microcontroller or
provides GPS on-chip?
