GPS技术,是利用GPS卫星信号接收的,可以24小时不间断地接收卫星发送的数据参数结算出接收的三维位置、三维方向以及运动速度和时间信息。车载GPS导航仪,顾名思义,即是安装在车上,通过接收卫星信号,配合电子地图数据,适时掌握自己的方位与目的地。目前自主导航的模式不收取任何使用费用,用户可以根据自己的需要有选择地购买地图数据。一言蔽之,当使用者把车载GPS安装在车上后,无论使用者身处哪个城市、城镇或是郊区,我们都能在转瞬之间找到一家餐馆或是最近的一家加油站。虽然目前有些豪华和普通轿车车身自带了车载GPS,但对于玩车族尤其是户外越野爱好者们来说,那远远不能满足他们的需要。于是各种各样功能繁多的车载GPS导航仪就诞生了。这次,我选取了入门级的新科的400S、350C和宇达电通的C210进行评测。
GPS technology is the use of GPS satellite signals received, 24 hours a day can receive data sent by the satellite parameters to receive the settlement of the three-dimensional position, three-dimensional direction and velocity and time information. Car GPS Navigator, as its name implies, is installed in the car, by receiving satellite signals, with the electronic map data, timely grasp their own direction and destination. At present, autonomous navigation mode does not charge any user fees, and users can selectively purchase map data according to their needs. In a nutshell, when a user installs a car GPS on a car, we can find a restaurant or nearest gas station no matter which city, town or suburban area the user is in. Although some luxury and ordinary car body comes with a car GPS, but for car owners, especially outdoor off-road enthusiasts, that is far from meeting their needs. So a wide range of versatile car GPS navigator was born. This time, I selected the entry-level new section of the 400S, 350C and MIO C210 evaluation.
