Abstract:

Interpolation of the converted azimuth and elevation angle is required in the measurement and control equipment, and the interpolation method should be as simple as possible without affecting the accuracy of interpolation. The commonly used methods of the Lagrange interpolation, Newton interpolation, Neville interpolation and Aitken interpolation are introduced, and the effects of the interpolation points on the interpolation results by these four methods are analyzed．The conclusion is obtained through the calculation of a practical example. Finally, the advantages and disadvantages of the four methods are discussed. It is concluded that the Neville algorithm is the best interpolation for guiding the tracking interpolation of space measurement and control equipment．
