GPS module - advice needed

[ScaleRobotics]

Well, they don't spell it out too well in the data sheet. I think that it what they are referring to in "C/A Rate 1.023 hertz", but I guess I have read a lot on different forums about the em406a. Most receivers do the 1 hertz rate. So if it doesn't mention 5 or 10 hertz, you can assume it does 1 hertz.

Here is a little gps tutorial from Sparkfun. They also mention the em406a being 1 hertz. There is some good information here: http://www.sparkfun.com/commerce/tut...torials_id=127

Oooh! There is also a nice one here that does 10 hertz, but you need to get an external antenna. Might be good if you have a metal "cart". Then you can mount the antenna on top. http://www.sparkfun.com/commerce/pro...oducts_id=9133
