ASF Correction in Long-wave Time Service
Na Wang · Yuhang jice jishu · 2011
The Additional Secondary Factor(ASF) is the major factor affecting accuracy of long-wave time service.while its theoretical complexity and experimental costs too high,not easy to project promotion.The area of the North China Plain was selected as a research example,and a new method which establish ASF data grid and use interpolation algorithm to study the ASF correction was presented.The results obtained are consistent with expected.The experimental results show that: Established regional ASF data grid can help quickly correction ASF for practical engineering applications.
