Hello all,

I'm not sure if this is the right place to ask, but I think this is a good
place to start. I have been asked to write a small program, to run on a
laptop (or perhaps a PDA) that accepts log entries. They want several
fields captured, among them lat/long coordinates.

Is there a standard API for getting this info or will this need to be
written with a specific piece of GPS hardware in mind? I think I'm over my
head here. Any help would be appreciated.

Bill
 
Look up the NEMA specifications and you'll get a lot of info about the data
format (google for "nema gps"). The protocol isn't that complex, but there
are a bunch of variations. You might want to look at
http://www.gpsdotnet.com/, it's a commercial GPS .NET product, and will
handle most of the low-level stuff for you.
 
Hi,

GPS receivers output serial data using the NMEA-0183A protocol. Decoding
this is fairly straight forward. I have example code for both desktop and
Compact Framework in my book (see below). Also, you may download the
Compact Framework DLL -- free -- from my homepage.
