No problem. 5 or 10 updates per second are available on most GPS modules. I recommend the ublox 6,7 or 8 modules. 8 is the better one, at a little more.I do not recommend the Venus brand. MTK/Global Top is ok, but the cheapest GPS modules (nonames) can have other issues.
can you post a link to the product so that I can look at the product you suggested, a lot of different things came up on amazon.com when I checked
