This proposal describes plans to complete the connection of all VLBA stations to an optical fiber network. Upon completion the VLBA data network capacity will be increased to 200 Mbps. Such capacity will allow improved diagnostic and time-critical observing capabilities. Upgrades to the VLBA data network is the first step in a three-phased approach to allow real-time observations. Improved connectivity that optical fiber provides will increase the scientific utility of the VLBA for the US and global scientific community. Improving the data capabilities of the VLBA by installing/operating optical fiber to all sites will greatly enhance its capabilities, opening additional areas of VLBA research and extend the distance ranges, both within the Galaxy and throughout the Universe, at which the VLBA can make unique scientific contributions. The VLBA is uniquely situated to increase participation of traditionally under-served and underrepresented communities in the full spectrum of fields associated with radio astronomy. With 10 sites located across eight states and the U.S. Virgin Islands, the VLBA offers research and educational exchange opportunities to a broad cross section of the U.S. student population, including students who live and study in areas of the country in which targeted efforts are made to broaden participation of diverse individuals in STEM education, training, and professional development. In addition, VLBA observations are vital to maintaining awareness of Earth's orientation in space, a parameter of key importance in operation of the Global Positioning System for example.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.

该提案描述了完成所有VLBA站与光纤网络连接的计划。 建成后，VLBA数据网络容量将增加到200 Mbps。 这种能力将有助于提高诊断和时间紧迫的观测能力。 VLBA数据网络的升级是实现实时观测的三阶段方法的第一步。 光纤提供的更好的连接性将增加VLBA在美国和全球科学界的科学效用。通过在所有站点安装/操作光纤来提高VLBA的数据能力，将大大增强其能力，开辟VLBA研究的其他领域，并扩展VLBA可以在银河系内和整个宇宙中做出独特科学贡献的距离范围。 VLBA具有独特的地位，可以增加传统上服务不足和代表性不足的社区在与射电天文学相关的所有领域的参与。VLBA在八个州和美属维尔京群岛设有10个站点，为广泛的美国学生群体提供研究和教育交流机会，包括在该国有针对性地努力扩大不同个人参与STEM教育，培训和专业发展的地区生活和学习的学生。 此外，VLBA观测对于保持对地球在太空中的方位的认识至关重要，例如，这是全球定位系统运行中的一个关键重要参数。该奖项反映了NSF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。
