The investigators will build a facility for imaging high-energy electron precipitation and remote sensing high-energy particle dynamics in near-Earth space. They will design, test, and build a synchronous direct digital receiver that will form the foundation of the next-generation VLF-HF (Very Low Frequency/High Frequency) receivers/riometers. Using this technology and in collaboration with Canadian investigators, the researchers will deploy an array of these receivers to establish a comprehensive network of digital imaging riometers that will build international partnerships, take advantage of existing (and planned) networks of complementary instruments, and enable new and exciting science. The timely deployment of the riometer network will also be enhanced by synergies with space-based observations of the near-Earth geospace environment, such as NASA's Magnetospheric Multiscale (MMS) and Radiation Belt Storm Probes (RBSP) missions, as well as ESA's Swarm. The data and engineering study results from this effort will be made available to all researchers. All design documentation will be posted on the project website so that duplicate systems can be easily constructed. The engineering design work will be integrated into undergraduate curriculum, including independent studies and experimental courses.

研究人员将建立一个设施，用于对近地空间的高能电子沉淀和遥感高能粒子动力学进行成像。他们将设计、测试和构建一个同步直接数字接收机，该接收机将成为下一代甚低频/高频（VLF-HF）接收机/测距仪的基础。利用这项技术并与加拿大研究人员合作，研究人员将部署一系列这些接收器，以建立一个全面的数字成像riometers网络，建立国际合作伙伴关系，利用现有（和计划）的互补仪器网络，并实现新的和令人兴奋的科学。riometer网络的及时部署也将通过与近地地球空间环境天基观测的协同作用得到加强，如美国航天局的磁层多尺度和辐射带风暴探测器任务以及欧空局的Swarm。 这项工作的数据和工程研究结果将提供给所有研究人员。 所有设计文件都将张贴在项目网站上，以便可以很容易地建造重复的系统。工程设计工作将纳入本科课程，包括独立研究和实验课程。
