即将到来的卫星服务向更高波段即Ka波段和Q波段的转移在带宽、数据速率和系统容量方面提供了许多优势。然而，它带来了挑战，因为由各种大气现象引入的传播效应在这些频带中特别明显，并且可能成为系统可靠性和性能方面的严重限制。本文概述了目标，组织和一些正在进行的大型传播活动财团在欧洲形成的欧洲航天局的监督下的第一批成果;该运动，最终将有助于验证和开发针对这些波段的信道模型。最后，考虑不同的气候条件和仰角沿着频率和时空效应的评估，应支持衰落和缓解技术的开发及其使用真实的数据的评估。
The upcoming migration of satellite services to higher bands, namely the Ka- and Q-bands offers many advantages in terms of bandwidth, data rates and system capacity. However, it poses challenges as propagation effects introduced by the various atmospheric phenomena are particularly pronounced in these bands and can become a serious constraint in terms of system reliability and performance. This paper outlines the goals, organization and some first results of an ongoing large propagation campaign consortium formed across Europe under the supervision of the European Space Agency; the campaign, shall ultimately assist in the validation and development of channel models targeting these-bands. Finally, the consideration of diverse climatic conditions and elevation angles along with the evaluation of the frequency and spatio-temporal effects, shall support the development of Fading and Mitigation Techniques and their assessment using real data.
