International Workshop on Space Weather Effects on Communications and Navigation Signals; Boston, Massachusetts, June 7 - 8, 2001

该奖项支持2001年6月7-8日在马萨诸塞州波士顿举行的空间天气对通信和导航信号影响国际研讨会。主要组织者是波士顿学院的塞萨尔·瓦拉达雷斯教授。这次为期两天的研讨会紧随国际无线电科学家联盟（URSI）的国际信标卫星研讨会之后，将促进来自美国、加拿大、欧洲、南美、中国、台湾、印度和非洲的研究人员之间的讨论。讨论的主要议题是电离层对天基通信和导航系统的影响。在全体会议介绍之后，讲习班和海报会议将提供机会就世界和区域电离层问题以及目前旨在评估和了解电离层对天基系统影响的研究活动交流信息。范围：全球定位系统（GPS）最初是由国防部作为军事系统开发的，现已成为全球公用事业。全球定位系统的转换使其在全球民用用户中的精度得到了显著提高。应用包括航空、公路、海洋和铁路导航、电信、应急响应、石油勘探、采矿等等。讲习班将为交流美国和欧洲就利用全球定位系统进行天基导航和通信系统开发的知识提供一个论坛。同样，来自赤道各国的同事将能够分享他们对当地电离层状况和当前研究活动的了解。该研讨会为国际同行制定研究议程以了解电离层对天基系统的影响提供了一个独特的机会。该奖项由国际项目部和大气科学部联合支持

The principal organizer is Professor Cesar Valladares of Boston College. The two-day workshop, which immediately follows the International Beacon Satellite Symposium of the International Union of Radio Scientists (URSI), will promote discussion among researchers from the United States, Canada, Europe, South America, China, Taiwan, India, and Africa. The prime topic for discussion is the ionospheric effects on space-based communication and navigation systems. Following the plenary presentations, workshop and poster sessions will provide the opportunity to exchange information on worldwide and regional ionospheric problems and on current research activities aimed to assess and understand ionospheric effects on space-based systems.Scope: The Global Positioning System (GPS), which originally was developed by the Department of Defense as a military system, has become a global utility. Conversion of the GPS has resulted in dramatic improvement in its accuracy for civilian users worldwide. Applications include air, road, marine, and rail navigation, telecommunications, emergency response, oil exploration, mining, and many more. The workshop will provide a forum for the exchange of knowledge developed in the United States and Europe on utilizing the GPS for space-based navigation and communication systems. Likewise, colleagues from various equatorial countries will be able to share their knowledge of local ionospheric conditions and current research activities. The workshop offers a unique opportunity for international colleagues to develop a research agenda for understanding ionospheric effects on space-based systems. This award is jointly supported by the Division of International Programs and the Division of Atmospheric Sciences
