Performance assessment of interpolation methods for orbits of altimetry satellites

HIGHLIGHTS

• What: The authors investigate the appropriate method and its degree to reduce errors to sub-millimetre levels. The analyses conducted in this study provide good results for of degrees 7-11 and of at least degree 9 with a three-dimensional error of 0.6 mm and a scattering of 0.2 mm on average for coordinates given with an accuracy of 1 mm in the SP3 format. The authors investigate the suitability of common interpolation approaches and analyse which methods fulfil the high demands of_(sub-)millimetre accuracy for the interpolation of altimetry satellite orbits.
