设专门课题 日本启动汽车高精度GPS研发 目前,移动体使用的GPS(全球定位系统)精度的最大误差为数10米,有些领域正在把实现更高精度GPS作为争取目标。汽车导航装置使用的车载GPS的最大误差也是数10米,在实际使用中尚无问题。当前,也还没有进一步提高精度要求。但是,在采用保持车线汽车自动行驶等技术方面和做为未来ITS(智能交通体系)中汽车用创新设备,提高GPS精度等级就是必要的课题,这也意味着GPS的不断技术进步。为此,JSK(日本
Setting Special Topics Japan Launches High-Precision GPS R & D Currently, the maximum error of GPS (Global Positioning System) accuracy used by mobiles is 10 meters. Some areas are trying to achieve higher-precision GPS. Car navigation device using the maximum error of the car GPS is also a few 10 meters, there is no problem in actual use. At present, no further improvement in accuracy is required. However, improving the level of GPS accuracy is an important issue in technologies such as auto-driving to maintain the car line and as an innovative device for automotive use in the future ITS (Intelligent Transport System), which means that GPS technology continues to improve. To this end, JSK (Japan
