| 摘 要： | 在GPS单点定位和相对定位中都需要不断计算卫星的坐标。IGS提供的精密星历为15min间隔，要得到更小间隔的数据，就要进行插值。利用广义延拓插值进行GPS精密星历插值，探讨插值精度与三个参数的关系，并与Lagrange多项式插值和三角插值结果进行比较。结果表明，广义延拓插值法具有较高的精度，完全适用于精密星历的插值。

| Abstract: | In GPS point positioning and relative positioning,it needs to calculate the coordinates of the satellites.IGS provided precise ephemeris at 15 minute intervals,in order to get much smaller interval,it is necessary to carry out interpolation.The generalized extension interpolation is used to interpolate the IGS percise epheneris.Besides,discuss the interpolation accuracy and the relationship with the three parameters,the results are compared with Lagrange polynomial interpolation and trigonometric interpolat... |
