GIS Software for ASF Correction in Timing of Long-wave
KE Xi-lin · Yuhang jice jishu · 2007
The multi-resource datas which are geo-information data,ground electronic parameter data and atmosphere refractive index,have been integrated and visualized fast in the GIS software for ASF corredion in timing of long-wave.The ASF and the ground propagation delay of long-wave signal from many stations in different typical path for wide area,can be easy calculated and improved in timing accu- racy with different model by this GIS software.
