Short summary

The Submillimetre Wave Instrument (SWI) aboard the Juice mission is a sophisticated and first-of-its-kind payload. SWI is designed to support the diverse science objectives of the Juice mission targeting Jupiter's middle atmosphere, icy-moon's exospheres as well as near sub-surface thermophysical properties. This presents significant planning, operations and commanding challenges which are described in this paper in the context of the Lunar and Earth Gravity Assist (LEGA).
