Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

 


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.
