According to the processing need of calibration data for part telemetry slow-changing parameters,the regression processing method to use is puts forward in this paper. The principle of the smooth unequally-spaced interpolation algorithm is elaborated. The software processing flow of the algorithm is introduced. The verification analysis for this algorithm is performed with experimental data. It is proved that the algorithm has perfect smoothness and high accuracy. The precision value at any point can be derived by the unique interpolation polynomial of every subset. The shortages of spline interpolation method and the entire polynomial were overcome. The test result shows that the algorithm is suitable for processing any kinds of slow changing parameters when the calibration data is non-linear.
