HARMONICS: A visualization tool for Hayabusa and Hayabusa 2 missions

Abstract

We developed a tool for visualizing the spatial geometry of objects and field-of-view (FOV) of scientific instruments for mission plans and data analysis of Hayabusa and Hayabusa 2, and named "HARMONICS (Hayabusa Remote MONItoring and Commanding System)." We also implemented a graphical user interface to simulate a changing FOV. Displaying arbitrary viewpoints over a time sequence helps determine the geometry observed and supports later data analysis. HARMONICS loads ancillary data with the SPICE kernel format: position and attitude of the spacecraft, properties of scientific instruments and target's shape model, etc. Here, we report on the system details and enhanced functions of HARMONICS compared to the original version in 2005.
