摘要
针对CORS升级改造成本问题,新系统测试和新增建设基站期间新旧系统并行运行问题,基准站位置变化监测问题,正常高测量问题,本文以KMCORS升级改造实践为例,提出了一种CORS升级改造技术问题的解决办法。利用旧CORS系统部分硬件设施,以节约改造成本;用功分器和两套IP地址,以解决新系统测试期间新旧系统并行运行问题;新增建设基岩观测墩,以解决地壳变形相对位移问题;用已有二等水准点作为高程异常控制点,获得似大地水准面精化模型,以解决网络RTK正常高测量问题。该方法在KMCORS升级改造实践中得到了验证,证明该方法是正确可行的,值得高原地区和经济欠发达地区CORS升级改造借鉴。
Aiming cost problem of CORS upgrading and reconstruction,new and old systems running problems in parallel during new system test and new build reference station,monitoring problem of reference station location change,monitoring issues,normal high measurement problem,the paper take KMCORS upgrading and reconstruction practice as an example proposed a solutions of CORS upgrading and reconstruction.Use the old CORS part of the hardware to reduce the cost of remolding,use power divider and two sets of IP addresses to solve the problem of running parallel to the old system and new system during the new system test,a new bedrock observation pillar is added to solve the relative displacement problem of crustal deformation,using the existing second-level benchmark as the height anomaly control point,obtain the precise model,to solve the normal high measurement problem of network RTK.This method is verified in the practice of KMCORS upgrading and reconstruction,the method is proved to be correct and feasible.The method is worthy of reference for CORS upgrading and reconstruction in plateau section and less developed regions.
