摘要
随着我国北斗卫星导航系统向整个亚太地区提供高精度的定位导航服务,推进北斗卫星导航产业应用已成为测绘与地理信息行业的重要目标。当前浙江省已经建成覆盖全省的北斗地基增强系统框架网络,并基于该网络完成了一系列测试工作。测试结果表明,其对应浙江省北斗地基增强系统设计指标平面不大于5cm,高程不大于10cm标准,不论国产主板设备、进口主板设备其平面精度指标都能够基本满足设计要求,但高程精度设计有所欠缺,北斗地基增强系统在提供连续、可靠高精度厘米级差分应用服务方面依然有待突破。
With China's Beidou satellite navigation system to provide high-precision positioning and navigation services to the whole Asia-Pacific region,the application of Beidou satellite navigation industry has becoming an important goal of surveying and mapping and geographic information industry.At present,Zhejiang province has completed the big dipper system framework network,and completed a series of tests,test results show that the design index plane is less than 5cm,height is less than 10 cm,regardless of domestic motherboard equipment,import motherboard equipment plane accuracy index basically all can meet design requirements.But the elevation accuracy design is short,the Beidou foundation enhancement system is still needs to be broken.
