本文介绍Juice任务中SWI仪器在月球-地球引力辅助期间的操作挑战与校准策略，利用LEGA验证未来冰卫星飞越的操作方案。
AI 中文摘要
木星冰月探测器（Juice）于2023年开始了为期8年的前往木星及其冰卫星的行星际旅程。亚毫米波仪器（SWI）是航天器上搭载的十台科学仪器之一。SWI是首个访问外太阳系的此类先进载荷，具有双频段可调接收器、两个独立指向机制以及能够实现高分辨率（分辨率高达10^7）的光谱仪。它旨在支持Juice任务针对木星中层大气、冰卫星的外逸层以及近地表热物理性质的各种科学目标。为此，Juice任务在木星系统内采用了复杂的轨道巡游轨迹，这进一步要求为SWI制定复杂的、任务驱动的操作概念。这带来了重大的规划、操作和指令挑战，本文在月球和地球引力辅助（LEGA）的背景下描述了这些挑战。在仪器开发和地面校准之后，SWI团队设计了一套全面的校准策略，适用于Juice巡航阶段。在包括近地调试阶段和十多个有效载荷检查窗口在内的各种校准机会中，LEGA不仅提供了改进仪器校准的手段，还验证了未来冰卫星飞越的操作策略。
英文摘要
The Jupiter Icy Moons Explorer (Juice) embarked in 2023 on a 8-year interplanetary journey to Jupiter and its icy moons. The Submillimetre Wave Instrument (SWI) is one of the ten science instruments aboard the spacecraft. SWI is a sophisticated and first-of-its-kind payload visiting the outer solar system, featuring dual-band tunable receivers, two independent pointing mechanisms, and spectrometers capable of high resolution (up to a resolving power of 10^{7}). It 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. For this purpose the Juice mission adopts a complex trajectory tour within the Jovian system, which further necessitates a sophisticated, mission-driven operations concept for SWI. 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). After the development and ground calibration of the instrument, the SWI Team has designed a comprehensive calibration strategy applicable during the Cruise Phase of Juice. Among the various opportunities for calibration, including the Near-Earth Commissioning Phase and more than ten Payload Checkout Windows, the LEGA offers the means not only to improve the calibration of the instrument, but also to validate the operational strategy of future icy moon flybys.
