GPS Resources

For some NGOs, GPS units have become indispensable for field and emergency work. In the old days, companies like Garmin and Magellan had a virtual monopoly on the GPS market, and there were only a limited number of products you could purchase. However within the past few years, the consumer market has literally exploded, and there are a bewildering number of GPS units available with new technology advances appearing almost weekly.

If you want to keep up with what's happening in the GPS world (or need advice on what type of a unit to select), I recommend three Web resources. GPSInformation.net is one of the oldest GPS sites on the Net, and provides reviews, firmware update news and general information. GPS Passion is a European site that features GPS news, reviews and discussion forums. NaviGadget is a blog that provides extensive coverage of the latest GPS devices to hit the market.

Each of these sites provides unique information, so if you're interested in GPS, be sure to give all of them a quick look.
