Title: GPS thoughts
Post by: Admin on March 08, 2007, 03:09:32 PM

as GPS electronics gets cheaper and easier to work with, ive been thinking about trying it out within the next year or two . . .

the latest one here looks pretty nice:

it even claims it could track 9 satellites indoors!

anyone have experience interfacing a GPS to a microcontroller and have thoughts on it to offer to GPS beginners?

I've yet to see a GPS that works indoors, so if this is the exception, I'd be impressed.

The GPS I have tried generate a more or less continuous 4800 baud stream of data, so you need a serial interface.  It's not particularly difficult to decode the data stream.
