摘要：

The Hermite interpolation is foundation of spline interpolation, and it has very strong adaptability and controllability. In GPS position calculation, if we can use suitable method to calculate the derivative at nodes, the Hermite interpolation function can be proposed, which has Cl continuity and consistent convergence. This paper introduces piecewise low Hermite interpolation algorithm and interpolates the broadcast ephemeris. Experiment results show this algorithm can satisfy the precision, avoid some shortcoming and is worth of generalizing at a certain extent.
