2005年1月14日惠更斯大气探测器在土卫六执行使命前后或期间，对土卫六进行了协调的地面观测，将探测器的瞬时现场观测与持续的地面方案提供的天气覆盖联系起来。这些观测包括三个不同的类别：（1）射电望远镜在2040 MHz跟踪惠更斯信号，（2）观测土卫六的大气层和表面，（3）试图观测惠更斯探测器进入土卫六大气层时发出的辐射。探测器的无线电信号被一个地面望远镜网络成功获取，恢复了土卫六大气层中从140公里高度到表面的风速垂直分布。地面观测带来了关于土星最大卫星的大气和表面特性的新信息。未报告与穿刺针进入相关的阳性检测现象。本文回顾了所有这些措施，并强调取得的成果。地面观测，包括无线电观测和光学观测，对于解释惠更斯使命的结果至关重要。
Coordinated ground-based observations of Titan were performed around or during the Huygens atmospheric probe mission at Titan on 14 January 2005, connecting the momentary in situ observations by the probe with the synoptic coverage provided by continuing ground-based programs. These observations consisted of three different categories: (1) radio telescope tracking of the Huygens signal at 2040 MHz, (2) observations of the atmosphere and surface of Titan, and (3) attempts to observe radiation emitted during the Huygens Probe entry into Titan's atmosphere. The Probe radio signal was successfully acquired by a network of terrestrial telescopes, recovering a vertical profile of wind speed in Titan's atmosphere from 140 km altitude down to the surface. Ground-based observations brought new information on atmosphere and surface properties of the largest Saturnian moon. No positive detection of phenomena associated with the Probe entry was reported. This paper reviews all these measurements and highlights the achieved results. The ground-based observations, both radio and optical, are of fundamental importance for the interpretation of results from the Huygens mission.
