If you have a Web-enabled cell phone or PDA, you can receive instant street maps of your current location with a subscription software package from Handmark. This service for people who don't have GPS receivers returns precise maps based on street and city queries that you send wirelessly. You can also get up-to-the-minute news, weather (with live radar maps), sports, stock prices, directories, and movie times and ticket purchases. The street maps can help you avoid having to ask for directions; but aside from that, the service's unlimited directory assistance (with reverse directories as well) more than justifies the $70 yearly subscription. For $30 a year, you can obtain just mapping and directory assistance.

A GPS (global positioning system) receiver can't function if it can't see the satellite, so position it as carefully as possible to get a clear view to the sky. Move away from trees, buildings, hydro wires, and other people and let the device orient itself before trying to take an important reading. In fact, whenever you change direction as you move, reposition the GPS receiver to give it the best chance of connecting to the satellite signal. GPS devices need a bit of help if they're to give you the quality of information you require.

What extra features are there? Extra functions are available in many GPS tracking devices, an example of this is using you in-car GPS system�s speakers as a hands free for a cell phone. These extra functions can make your life much safer, but do you need them? As appealing as it may be, don�t go for the GPS tracking device or auto GPS system with the most features, many of them are unnecessary for your average lover of the outdoors or vehicle owner. At the other end of the spectrum you don�t want to buy a cheap model either. A quality GPS and GPS accessory kit is worth the investment. Otherwise, you might end up having to replace your GPS tracking device just as fast as you bought it.

Write Here, Write Now: And you thought you were overloaded with information now, just wait. Hewlett Packard is working on a technology to let folks print messages in mid-air based on their location incorporating GPS technology. I find this stuff fascinating, even if no one seems to have thought of a good use for it yet.

When the ALA summer conference was in San Francisco in 1997, the SF Museum of Modern Art had a fascinating exhibit called Icons: Magnets of Meaning. I spent hours browsing through it, but one of the pieces that has always stuck in my mind was called @: Marking the Electrosphere . It talked about the meaning of that one little symbol. How it can define, place, and root you in the world, but at the same time let you be found anywhere. Integrated, widespread use of GPS is going to take this to a whole new level.
