35、uters, now sold by most car makers, cost $ 2000 and up. No surprise, then, that they are most often found in luxury cars, like Lexus, BMW and Audi. But it is a developing technology-meaning prices should eventually drop-and the market does seem to be growing. Even at current prices, a navigation com
36、puter is impressive, It can guide you from point to point in most major cities with precise turn by-turn directions spoken by a clear human sounding voice, and written on a screen in front of the driver. The computer works with an antenna that takes signals from no fewer than three of the 24 Global
37、Positioning System (GPS) satellites. By measuring the time required for a signal to travel between the satellites and the antenna, the cars location can be pinned down within 100 meters. The satellite signals, along with inputs on speed from a wheel speed sensor and direction from a meter, determine
38、 the cars position even as it moves. This information is combined with a map database. Streets, land marks and points of interest are included. Most systems are basically identical. The differences come in hardware-the way the computer accepts the drivers request for directions and the way it presen
39、ts the driving instructions. On most systems, a driver enters a desired address, motorway junction or point of interest via a touch screen or disc. But the Lexus screen goes a step further: you can point to any spot on the map screen and get directions to it. BMWs system offers set of cross hairs th
40、at can be moved across the map (you have several Choices of map scale) to pick a point youd like to get to. Audis screen can be switched to TV reception. Even the voices that recite the directions can differ, with better systems like BMWs and Lexuss having a wider vocabulary. The instructions are av
41、ailable in French, German, Spanish, Dutch arid, Italian, as well as English. The driver can also choose parameters for determining the route: fastest, shortest or no freeways, for example. （分数：1.00）(1).We learn from the passage that navigation computers _.（分数：0.20）A.will greatly promote sales of aut
