What My Satellite GPS Can Do That Your Road Atlas Cant

By Christine Peppler

Television is not the only 'cool' thing using satellites these days. For anyone who likes to travel or wander, the GPS satellite navigation systems that have been on the market for a few years are handy on-the-road companions. Some automotive manufacturers offer GPS in select car models however GPS can also be purchased after market and can be operated outside of the car as well. Satellite GPS navigates through signals received from the myriad of satellites orbiting earth and is extremely accurate using the maps that are loaded into its memory.

So what does a satellite GPS device offer that a road atlas doesnt? GPS satellite systems provide directions while traveling, generally through voice instructions which allow the person to keep their eyes on the road. No more pulling off to the side of the road to study a map, struggling to read illegible print, or trying to find just the right spot with only a dome light for illumination.

Satellite GPS devices are also 'smart' as many can also provide updates on weather and traffic information and then assist in mapping an alternate route when barriers exist in the pre-planned route. This flexibility and problem solving make it an invaluable tool when traveling in an unfamiliar area.

Satellite GPS devices are also great to use when hiking, camping, cross country skiing, and participating in similar outdoor activities. Their small size and light weight make them a great tool outside of the car and are often recommended by outdoor enthusiasts and organizations for safety purposes.

Most satellite GPS devices sold in the US contain maps and points of interest such as airports, hospitals, and so forth to the tune of over one million locations. However, these devices arent limited to the boundaries of the US obviously. For those who wish to use the device when traveling outside the country, many devices have flash cards which can be used to download the appropriate maps corresponding with their destination making satellite GPS a great travel companion.

For many potential users an important consideration is ease of use. Many satellite GPS devices, such as the portable Sony Nav-U, are ready to use right out of the box. It has maps and over 1.6 million points of interest loaded into its memory. It offers a full color 3.5' touch screen display and 2-way speaker system. Cost of an average satellite GPS device is in the range of $400 to $600 dollars but given years of good service and flexibility of use it would seem an excellent investment.

In the world of navigation or route finding, it seems that satellite GPS devices will eventually put basic road maps and compasses into the same realm as typewriters and carbon paper.

Qualcomm's Vision of the Wireless Future "When he finished, there were 20 brand-new, CDMA-based mobile handsets and devices arrayed on the table, the high-tech souvenirs of Belk's most recent trip to Hong Kong and Japan.... 'These are not PowerPoint slides,' Belk said. 'These are real devices that are already shipping in volume in Asia.' " at Business 2.0]

And there's the rub. When I do my presentations, that's all I have - pictures of prototypes or of devices not available in the U.S. Europe and Asia really are 18 months ahead of us in this area.

"Beale also discussed Qualcomm's gpsOne location technology.... It also opens the door for many new location-based services, such as traffic information and local weather forecasts. On Japan KDDI's network, there are already more than 20 location-based services available -- all of which are relatively inexpensive, costing less than $5 per month."

I'm looking forward to being able to travel and have information come to me automatically based on my location. For example, if I'm at a conference and I'm looking for a restaurant, I'd like my phone/PDA/whatever to know where I am and offer a list of nearby choices. Maybe it should tell me what movies or plays are on tonight and if there are still tickets available. You get the idea....

"Predictably, both Belk and Beale anticipate strong growth for the wireless industry as ever-more-compelling products and services become available and the industry settles on a single communication standard. How long will that take? Belk, whose career began in the personal computing business in 1983, likened the wireless industry today to the PC business of the 1980s. 'I wouldn't worry about the wireless industry yet, it's still relatively young,' he said. 'Just look how long it took the PC industry just to get to the point of standardized parallel cables.' "

Not to beat a dead horse, but the ebook industry is even younger than PCs, and PDAs have really only come into their own during the last few years. So don't count any of these technologies out just yet.

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. The first sentence of the article is right, though: "The kids are going to love this." in New Scientist via RCPL's Liblog]

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.

Lots of interesting articles from today's PC World. First up, Microsoft Takes on MapQuest: "MSN launches MapPoint online mapping service, offering maps, directions, and more."

Apparently this is going to be yet another component of MS' push for .Net services with hooks into other MSN services. MapPoint is XML-based, which makes it interesting in other ways, and there it launches with a phone-based direction service. The articles notes that this is another step towards location-based services. "For example, you might someday be able to click on a Windows Messenger buddy's name and retrieve a map showing the location of his or her home."

Good or bad? You make the call. I like parts of this, but I'm incredibly wary of .Net.
