摘要

在上述三个任务中常见的一项核心技术是NASA先进深空系统开发计划(ADSSDP)下正在开发的航空电子系统。ADSSDP公司首批交付的产品之一是X2000航空电子系统架构,其中包括主要工程计算系统、姿态控制传感器、电力电子设备和用于在地面测试和飞行中操作航天器的核心软件。航空电子硬件技术利用一组具有标准接口的多芯片模块之间的功能集成来实现更低的生产成本、功耗和质量。此外,包装密度的改进允许减少欧罗巴轨道器电子设备在强烈的木星辐射带中生存所需的屏蔽质量。

From the Sun to Pluto
A core piece of technology which is common amongst three missions described is the avionics system being developed under NASA's Advanced Deep Space Systems Development Program (ADSSDP). One of the first deliveries from ADSSDP is the X2000 avionics architecture which includes the main engineering computing system, the attitude control sensors, the power electronics and the core software used to operate the spacecraft in ground test and in flight. The avionics hardware technology utilizes integration of functions among a set of multichip modules with standard interfaces to achieve lower production costs, power and mass. Additionally, the packaging density improvements allow the reduction of the shielding mass required for the survival of the Europa Orbiter electronics within the intense Jupiter radiation belts.
