摘要
研究了LS-SVM用于GPS高程拟合的方法,针对京沪高速铁路某段GPS水准数据的特点,提出了基于LS-SVM的GPS高程拟合方案,并对试验结果进行了深入分析。结果表明,LS-SVM在GPS高程拟合方面能取得较好的效果。
The method of GPS height conversion based on LS-SVM is studied,and an elevation fitting procedure is proposed based on the characteristics of GPS-leveling data at a segment of Beijing-Shanghai high-speed railway.The results show that the GPS height conversion based on LS-SVM has a good performance.
