摘要

作为美国宇航局新前沿计划的重要组成部分,木星极地轨道器(朱诺)任务旨在深入研究木星的物理特性。它将包括这颗巨大行星的冰岩核心和大气研究,以及对其极地磁层的探索。它还将为了解木星磁场的起源提供机会。由于木星系统的恶劣辐射环境,该任务本身就对姿态控制系统(ACS)的设计提出了重大的技术挑战,因为ACS传感器必须在整个任务期间存活并正常工作,以可靠地操纵航天器。对不同的陀螺仪技术及其关键性能特性进行了讨论、比较和评估,以便于在恶劣的木星环境中选择合适的陀螺仪惯性测量单元,以确保任务的成功。

Gyro Evaluation for the Mission to Jupiter
As an important component in NASA's new frontiers program, the Jupiter polar orbiter (Juno) mission is designed to investigate in-depth physical properties of Jupiter. It will include the giant planet's ice-rock core and atmospheric studies as well as exploration of its polar magnetosphere. It will also provide the opportunity to understand the origin of the Jovian magnetic field. Due to severe radiation environment of the Jovian system, this mission inherently presents a significant technical challenge to attitude control system (ACS) design since the ACS sensors must survive and function properly to reliably maneuver the spacecraft throughout the mission. Different gyro technologies and their critical performance characteristics are discussed, compared and evaluated to facilitate a choice of appropriate gyro-based inertial measurement unit to operate in a harsh Jovian environment to assure mission success.
