3 DView IMPEx A 3 D orbit and attitude visualization tool Michel GANGLOFF CNRS IRAP Toulouse, FRANCE
q 3 DView provides displays of time interpolated orbit and attitude data of S/C and planetary ephemerides. q 3 DView was first designed for Rosetta mission in 2005 q In 2006 the product became 3 DView Multimission by taking into account other interplanetary missions, and many improvements 10/30/2020 2
3 DView is a tool for scientists useful in q Science data analysis and interpretation, e. g. : ü S/C localization ü Correlations between complementary missions ü Special events as planet or spacecraft conjunctions q Science operations planning ü Instrument ponting and FOV simulation q Conferences and outreach q Education 10/30/2020 3
q 3 DView is a lightweight, interactive and intuitive software q Free public access q 3 DView is scalable in order to meet user specific needs q Add artificial and natural objects q 3 D environment models ( e. g. magnetic fields) q Available at http: //3 dview. cesr. fr 10/30/2020 4

NEW DEVELOPMENTS IN 3 DVIEW A new version of 3 DView will be developed in the framework of IMPEx 10/30/2020 12
Goals and objectives of IMPEx Main goal Creation of an interactive computational framework where data from planetary missions are interconnected with numerical models to ① ② ③ ④ Simulate planetary phenomena and interpret space missions measurements Test models versus experimental data Fill gaps in the measurements by appropriate modelling runs Perform preparation of mission operations and solve technological tasks, including preparation of new missions 10/30/2020 13
IMPEx will enable – Selection, downloading, visualization and analysis of data from the modelling runs – Superimposing modelling data with spacecrafts measurements – Request of specific modelling runs – Scientific tools and functionalities for the support of preparation and operation of space missions (virtual spacecraft, visualizing expected observations from simulation databases) Background resources 10/30/2020 14
