| 摘 要： | 在GPS数据处理中,需要高采样率的精密卫星钟差,而IGS仅提供5 min间隔的卫星钟差,在实际应用中,必须内插出更小的采样间隔的数据。本文尝试将广义延拓法用于GPS精密卫星钟差插值,将5 min和15 min间隔的数据插值到30 s间隔,探讨插值精度与三个参数的关系,并将结果和GFZ提供的精密卫星钟差及其他插值方法得到的结果进行比较。结果表明,广义延拓插值法具有较高的精度,完全适用于GPS精密卫星钟差的插值。

| Abstract: | Several methods to interpolate precise satellite clock bias are introduced in this paper.And then,Generalized Extension Interpolation,for precise clock bias of GPS satellite is presented.The interpolation accuracy and the relationship with the three parameters are discussed.The results obtained by this method are compared with that from GFZ.The results calculated by this method show that the Generalized Extension Interpolation can get higher precision. |
