摘要
利用4个IGS参考站的观测数据,分析了RTKPOST的静态单基线、动态单基线、静态PPP、动态PPP的定位精度。结果表明,静态单基线解算和静态PPP的定位精度基本上能够达到现有相关软件的同等水平。动态单基线解算和动态PPP总体上能够达到cm级的定位精度,但存在滤波发散的问题,需要对算法进一步优化。此外,RTKPOST易于掌握和进行二次开发,可以在实际的测绘生产中根据不同的定位精度要求有选择地使用。
This issue mainly analyzed RTKPOST post-processing positioning accuracy of static single baseline,kinematic single baseline,static PPP and kinematic PPP by using four IGS reference stations data. The experimental results show that the positioning accuracy of static single baseline,static PPP mostly can reach the same level of existing software. Kinematic single baseline and kinematic PPP generally can reach unit of cm,but need to avoid filtering divergence by improving Kalman Filter algorithm. Furthermore,RTKPOST is very easy to master and second development,so which can be chosen to use in accordance with different positioning accuracy requirement during the realistic surveying and mapping production.
