摘要
针对海洋测绘中对GNSS差分定位的真实精度不确定而难以选择其方法的问题,以RTK常规差分、我国沿海的Beacon信标差分、覆盖亚洲的日本MSAS星站差分和中国精度ChinaCM星站差分为研究对象,对这几种差分定位方法的精度进行了验证和比较分析,实验结果可以为海洋测绘提供参考。
For solving the problem that it is difficult to choose the most appropriate method of GNSS differential positioning in marine surveying and charting due to the unknown real precision,the methods of RTK difference,beacon difference in China's coastal,Japan's MSAS difference of covering Asia and ChinaCM difference are introduced.By the actual measuring experiments,the positioning precision of every method above is verified.After the results of experiments are analyzed comparatively,the conclusions which is useful to marine surveying and charting are given.
