This question came to me as I was searching for a portable navigation GPS for my car. I wondered as I researched products why some offered WAAS while others did not. So I found myself wondering what the acronym meant and how having or not having it would affect the product’s performance.

I want to connect one of those USB-based GPS receivers to my laptop, or even use it stand-alone (battery-powered). It has to be accurate (way better than 10 meters or 30 feet accuracy, maybe an accuracy as good as 1 meter or 3 feet, or so). I need to purchase one of those tools from a website, so I need some good advice. Thanks for your time, good will, and answers.
