CORS基准站的稳定性分析与研究

Analysis and Study on the Stability of CORS Reference Station

CORS系统作为地理空间框架的重要基础设施,需向用户提供精确的三维定位服务。CORS系统基准网自身的稳定性是确保系统正常运行的关键。以广州CORS网为例,简要介绍了基准站网稳定性分析的流程,主要包括:数据整理准备、基线解算、平差计算、稳定性分析等,并最终得到可靠的分析成果。结果表明了该方法的可行性,对后续稳定性分析工作具有一定的指导意义。

CORS system as an important infrastructure of geo spatial framework ,pro-vides accurate three-dimensional positioning service to users .Stability standard of its ow n network of CORS system is the key to ensure the normal operation of the system .Based on the Guangzhou CORS network as an example ,briefly introduces the reference station net-work stability analysis process ,mainly including ：data preparation ,baseline solution ,the adjustment calculation ,stability analysis ,and get the final results reliable .T he results show that the method is feasible ,which has a certain guiding significance for future work stability analy sis .
