| Abstract: | We describe several popular interpolation and fitting algorithm in principle. Taking advantage of the Center IGS precise ephemeris given program as an example, the interpola- tion and fitting in the quality and efficiency of each operator method are eomparied and analzed. Finally, we analyze the experimental results through software of precise point positioning, and give some meaningful conclusions. |
