北斗系统厘米级定位是依靠地面增强接收站实现的,只限于局部地区可用,而本次的升级版导航芯片在北斗导航覆盖区域都能实现精度2.5米的定位,目前美军正在组建的GPS-IIF新一代卫星定位精度预计在3米内。中国航天科工集团所属中国航天科工信息技术研究院西安航天华迅公司成功研发出第四代高性能北斗GPS导航芯片。该芯片定位精度为2.5米,俘获灵敏度、跟踪灵敏度等各项性能指标达到国际领先水平。 Beidou centimeter-level positioning system is to rely on the ground to enhance the receiving station, only available in some areas, and this upgraded version of the navigation chip Beidou navigation coverage area can achieve the accuracy of 2.5 meters positioning, the current US military is being set up GPS-IIF A new generation of satellite positioning accuracy is expected within 3 meters. China Aerospace Science and Industry Corporation belongs to China Aerospace Science and Industry Information Technology Research Institute Xi’an Aerospace Huaxun successfully developed the fourth generation of high-performance Beidou GPS navigation chip. The chip positioning accuracy of 2.5 meters, capture sensitivity, tracking sensitivity and other performance indicators reached the international advanced level.
