Cassini Radio Science Subsystem (RSS) Small-Scale Atmospheric Features with Slepian Functions Bundle. - CERTIFIED


NASA Deep Space Network

Introduction

This dataset contains gravity field models of Saturn, derived from data collected during the Cassini Gravity Science Experiment from May to July 2017 (Rev 273, 274, 278, 280, 284). The solutions for Saturn’s gravity field are based on two approaches: a Slepian-combined method (using prolate spheroidal wave functions) and a spherical-harmonic-only method.
