I am doing some pretty heavy duty stuff with GPS at work, I am stumped. If anyone knows anything about the output from GPS' let me know. I need a 9600 baud output, and all I want from the NMEAA stream is the GPGGA (position). Looking for a GPS I can do this with, if anyone is a maven with these devices please pm me!

I'm far from being close to an expert but, all my Lowrance equipment has NMEA hookups. I had my Lowrance hooked up to the radar (Ray) on our big boat. Its been quite some time ago, but if I remember (age+time :rolleyes:) when you set it up, there's different settings you can use for different equipment needs. I remember that my Lowrance manual spelled it out pretty good, but I still needed to call Lowrance once to be sure of something. They handled it quickly.
Wish I could have been of better help. Good luck.

I have not done this for several years, but I have done it with a couple of different models by hooking up a USB connection from the GPS to a laptop computer. That allows you to use computer software to look at the ephemera (the raw data). This is probably more involved than what you had in mind, but if you really want to see the raw numbers it works. If I remember correctly, NMEAA is the basic interchange format for GPS data, so every unit "should" be able to provide it.

The reason that I have not this in a long time is that there are so many software packages (free and otherwise) that read the data directly. Just hook up the GPS to your laptop, have the software read your data stream and you have a map of where you went. (Use it when I'm 4-wheeling, and use a Topo map in the background so I know where I'm going and where I've been.) Probably does not help you if you are trying to do this at work.
