gps technical information

im in the need to design and develop a GPS receiver. but currently i
dont have much technical knowledge in the subject. im looking for some
internet resources where i can get a good understanding about the
implementation side of it (with out much theory).

hope someone can point some resources.


thanks.

You do know that you can buy the modules for ~$50 each nowadays. even
cheaper in Qtys.

The first site to mention about do-it-yourself GPS is of course Clifford
Kelley's:

Googling for "open source GPS" gives you a lot of interesting results:

(with out much theory).

Hmmm, that's gonna hurt. :)

As far as actually designing it, you may as well decide to climb
Everest with no mountaineering training. You can probably get a
reference design from one of the GPS chip-set makers, and basically
copy it.

What you need to look at is the NMEA protocol.
There is zero sense in designing a GPS yourself,
there are plenty of different modules on the market.

This seems like great. please let me know if you have any experiance
with this module.
thank you for the info.

I use a furono (Sp?) module that is bery similar but smaller. Very easy to
use. supply power and read the signal with the serial port on any uC.

The datasheet tells you which format. NMEA or binary. NMEA is good if you
plan on switching between GPS suppliers as it is a standard protocol. It is
"fluffy" though and is sent as ascii characters and you have to convert them
to binary befoure you can do any math in the parameters (if you need to).
Most modules also offer a binary mode that is already converted but eth
binary nodes are usually not standard across brands.

And there you have it. You can use modules, or you can learn a
shitpot of theory. Choose.
