摘要:

我们概述了行星射电干涉测量与多普勒实验(PRIDE)射电天文观测的运行和工程接口,该实验是ESA的木星冰卫星探测器(JUICE)任务以及其他未来行星与空间科学任务的科学组件。本文讨论了先进的调度和规划方法,使得能够为特定航天器观测与自然射电源观测的并发执行创建观测计划。为了将其付诸实践并为JUICE任务的PRIDE寻找合适的自然背景校准源,我们开发了规划和调度软件。传统的自然天体射电源调度软件无法在必要的控制文件中将航天器设为观测目标,因此在观测规划阶段就出现了困难。我们报告了用于卫星调度和规划的天体物理与大地测量VLBI新例程的开发及现有例程的适配。对PRIDE科学观测的分析改进了观测规划,并采用系统工程方法研究了任务的调度方法。此外,我们强调了新程序,如在多个频段范围内选择校准射电源的寻星图,以及这些策略在科学运行规划中的成果。基于Tudat软件对JUICE航天器巡航阶段金星飞越的模拟也予以展示,这为测试PRIDE技术及评估PRIDE观测量对自然天体星历的改进提供了一个极具前景的机会。

英文摘要:

We present an overview of the operations and engineering interface for Planetary Radio Interferometry and Doppler Experiment (PRIDE) radio astronomy observations as a scientific component of the ESA s Jupiter Icy Moons Explorer (JUICE) mission, as well as other prospective planetary and space science missions. The article discusses advanced scheduling and planning methods that make it possible to create observing schedules for observations of specific spacecraft in concurrence with observations of natural radio sources. In order to put this into practice and find suitable natural background calibrator sources for PRIDE of JUICE mission, we developed planning and scheduling software. The conventional scheduling software for natural celestial radio sources is not set up to include spacecraft as observation targets in the necessary control files. Therefore, difficulties already arise during observation planning. We report on the development of new and the adaptation of existing routines used in astrophysical and geodetic VLBI for satellite scheduling and planning. The analysis of the PRIDE science observations led to improved observational planning, and the mission s scheduling methodologies were studied using a systems engineering approach. In addition, we highlighted the new procedures, like finding charts for selecting calibrator radio sources over a range of frequency bands and the outcomes of those strategies for science operation planning. A simulation of the flyby of Venus during the cruise phase of the JUICE spacecraft, based on the Tudat software, is also presented, resulting in a promising opportunity to test PRIDE techniques and evaluate the improvements that PRIDE observables can make to natural bodies ephemerides.
