...increased. A spokesman attributed the dip to competition from the Web, and to the association's Map 'n Go software, a $60 navigation package that can be installed on PCs. If you want to get fancy, you can buy one of the car-based global-positioning devices, like StreetPilot GPS, by Garmin of Olathe, Kans., for under $550. Using signals from satellites, these devices tell you where you are and plot your course...
...Another souvenir Discovery brings home: A successful navigation experiment with Global Positioning System satellites. For the first time ever, the shuttle successfully received GPS data -- and that's something of a relief after a $33 million antimatter experiment was ruined Tuesday by communication breakdowns. Coming after the antenna malfunction that prevented TV broadcasts of their Mir hookup, the astronauts must have wondered whether their record of woes would outpace the Russian station's. Now the only thing they need worry about is storage space...
...have stolen submarine tracking software, and ominously promise to "prove it in early May." But how serious are the intrusions? Nobody knows yet, although the Pentagon says that no classified information was stolen. What has the DOD sweating right now is the safety of the Global Positioning System (GPS) -- and whether the MOD is doing more than simply taking a look around inside. Says TIME Pentagon correspondent Mark Thompson: "If these hackers can tinker with the GPS to a degree that all missiles based on it end up 10 miles from where they are supposed to be, or all ships...
Chouet is not the only researcher who's using the orbital high ground to study the volcanic underground. In Alaska, USGS researchers have placed satellite receivers at different points on the sloping side of the Augustine volcano and tuned them also to the gps. Like any volcanic mountain, Augustine is swelling slightly as it fills with magma. The degree of this deformation--as calculated by the gps--can help determine the imminence of the eruption. Elsewhere, scientists are leasing time on European or Japanese satellites to take photos of volcanic peaks as they undergo a seismic event like an earthquake...
Through the computer and the cell phones, drivers would receive destination instructions; using GPS, dispatchers would keep tabs on the real-time progress of each vehicle. Passengers would call up the service, be met with minimum delay, transfer only if necessary and relax while professional drivers took them to their desired destination -- say, that quaint little farmers' market on the far side of town, where the vegetables are always fresh but they don't take credit cards. In that case, you'd better hope there's an ATM around...
