近期卫星导航是业界的热点话题,这不但是因为北斗双星发射、第三届卫星导航学术年会在广州举行,也是因为新闻界热炒所谓的“导航仪合格率不到三成”。有关报道中提出,相当多导航仪触存在摸屏、电池容易损坏,找不到信号,地图陈旧,导航线路不合理等问题。但这里的问题显然要分成硬件和软件两部分来讨论。零部件质量差是导航仪的硬伤,任何企业用劣质零件拼装产品,都应该遭到市场的无情淘汰。但值得注意 Recent satellite navigation is a hot topic in the industry, not only because of the Beidou Double Star launch, the third satellite navigation academic annual meeting held in Guangzhou, but also because the media stir the so-called “navigation pass rate of less than 30%.” Relevant reports made quite a few navigators touching touch screen, the battery is easily damaged, can not find the signal, the map is outdated, the navigation route unreasonable and other issues. However, the problem here is clearly divided into two parts to discuss the hardware and software. Poor quality parts and components navigator flawed, any business with inferior parts assembled products, should be ruthless elimination of the market. But it is worth noting
