The International Beacon Satellite Symposium 2019; Olsztyn, Poland; August 18-23, 2019

该奖项为将于2019年8月18日至23日在波兰奥尔什廷瓦米亚和马祖里大学举行的国际信标卫星研讨会（BSS2019）提供支持。本次会议是一次重要的国际会议，特别关注利用地球上层大气无线电传播特性的通信和导航卫星。该奖项为参加会议的美国科学家和学生提供旅费和参会费用，并为来自发展中国家的非美国科学家提供生活支持。灯塔卫星研讨会为研究全球卫星星座的美国科学家和学生提供了一个独特的机会，让他们与来自世界各地的科学家会面，分享通过高层大气无线电传播的知识和对卫星技术的影响。本次研讨会是专门讨论卫星研究的首次国际研讨会。它为美国科学家和学生提供了无与伦比的好处，可以在全球范围内发展潜在的合作和伙伴关系，了解各自领域的国际进步，并在全球范围内分享他们的知识。随着成像和遥感技术、数据同化模型、分布式测量阵列、从空间监测自然灾害、国家和国际空间天气活动以及基于卫星的导航和通信系统的最新发展，利用卫星进行的研究获得了新的势头和前景。这次研讨会为美国科学家和学生提供了一个独特的机会，让他们从世界范围内了解这些研究课题的现状。它还将为全球合作和数据共享提供机会。最后，它可能为美国学生在全球实验室工作的国际交流提供机会。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award provides support for the International Beacon Satellite Symposium that will be held at the University of Warmia and Mazury in Olsztyn, Poland on August 18-23, 2019 (BSS2019). This meeting is an important international conference with a particular focus on communication and navigation satellites that exploit radio propagation properties of the Earth's upper atmosphere. The award provides travel support and participant expenses for US scientists and students to attend the conference as well as subsistence support for non-US scientists from developing countries. The Beacon Satellite Symposium provides a unique opportunity for US scientists and students working with global satellite constellations to meet scientists from all over the world to share knowledge on radio propagation through the upper atmosphere and implications for satellite techniques.This symposium is a premiere international symposium dedicated to satellite studies. It provides unparalleled benefits for US scientists and students to develop potential collaborations and partnerships worldwide, to learn of the international advancements in their fields, and to share their knowledge on a global scale. Studies using satellites have gained new momentum and perspectives with recent developments in imaging and remote sensing techniques, data assimilation models, distributed arrays of measurements, monitoring natural hazards from space, national and international space weather activities, and satellite-based navigation and communication systems. This symposium is a unique opportunity for US scientists and students to gain a worldwide perspective on the state of the art of these research topics. It will also present opportunities for global collaboration and data sharing. Finally, it may open opportunities for international exchange for US students to work in global laboratories.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
