RTK测量技术在三维地震勘探中的应用
|
摘要
1998年 10月至 1999年 2月 ,在松辽盆地南部十屋断陷秦家屯工区首次采用了卫星定位 1+5ASHTECHZ -FX双频型GPS .RTK接收机作业。在工区作业条件比较复杂情况下 ,共测定物理点 6 6 2 0 0个 ,测量作业 6 5d ,点位误差最大值 0 .4m ,精度小于允许值 ,没有系统误差。通过实践 ,表明该RTK测量技术测量点位准确、效率高、效益好 ,作业人员少 ,资料处理微机化程度高。该技术可广泛用于工程测量等测绘领域
From October 1998 to February 1999,the satellite positioning 1+5 ASHTECHZ FX dual frequency GPS·RTK receivers were firstly adopted for surveying in Qinjiatun working area of Shiwu Fault Depression in the south part of Songliao Basin.Under a complicated condition in the working area,66200 physical points in total were surveyed in 65 days,in which there was no system error and the maximum error of point location survey was 0.4m,being less than permissible value.It is shown that the RTK surveying technique if of many advantages,such as great accuracy,high efficiency,good economic benefit and high microcomputerization.So this technique can be widely applied to the survey and mapping domain as engineering survey,etc.
