The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to enable much-needed improvements to global position, navigation, and timing (PNT) services that are used by billions of people every day. The Earth’s atmosphere distorts PNT signals transmitted by satellites (i.e. global positioning systems, GPS), which lead to end user errors in position and time accuracy that are not easily removed. The goals of this project are to remove these atmospheric-derived errors in real-time at a system level. The effort will support novel global PNT services that will bring more precise global positioning and timing accuracy (less than 10 cm, less than 1 nanosecond) to end users in many downstream applications. Global precision timing from such a service will support the scaling up of intelligent transportation systems, making autonomous vehicles safer while driving down equipment costs. These autonomous vehicles include the projected millions of drones and automobiles that will be manufactured over the next several years. In addition, a global precision timing service, when available indoors, will reduce the deployment cost of millions of critical infrastructure devices in power, telecommunications, and financial sectors.This Small Business Innovation Research (SBIR) Phase II project seeks to accurately map the Earth’s troposphere and ionosphere and demonstrate autonomous satellite integrity monitoring using a constellation of small satellites. Proper mapping of the atmosphere may remove atmosphere-derived errors in space-based PNT systems. The first research objective is to expand the algorithmic and data processing framework for PNT satellites, called the Atmospheric Mapping and Satellite Integrity Monitoring System (AMSIM). The research will be adapted to real constraints of the system including spectrum and orbital configurations. The second research objective is to demonstrate the major elements of AMSIM on orbit, which will be accomplished with two demonstration satellites in Low Earth Orbit. The third research objective is to combine these factors to inform the true PNT performance of the production system so that it can be clearly conveyed to target end users. The anticipated technical results will be a commercially-viable and technically-feasible space system architecture enabling a precision global PNT system that can offer 10 cm and 1 nanosecond accuracies to end users.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.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力是，每天都有数十亿人使用的全球职位，导航和时机（PNT）服务的急需改进。地球的大气使PNT扭曲了卫星传输的信号（即全球定位系统，GPS），这导致最终用户的位置和时间准确性不容易消除。该项目的目标是在系统级别实时删除这些大气来的错误。这项工作将支持新颖的全球PNT服务，这些服务将带来更精确的全球定位和时机准确性（小于10厘米，小于1纳秒），以在许多下游应用程序中最终用户。从这种服务中获得的全球精确时机将支持扩大智能运输系统的扩展，从而使自动驾驶汽车更安全，同时降低设备成本。这些自动驾驶汽车包括预计将在未来几年生产的数百万次无人机和汽车。此外，如果在室内可用的情况下，一项全球精确的时机服务将降低数百万关键的基础架构设备的部署成本，电信，电信和财务部门。本小型企业创新研究（SBIR）II阶段项目旨在准确地绘制地球上的对流层和离子圈和小型卫星构成的组成型，以准确地绘制地球的对流层和IRESTOSTERITATINT sATERITE sATERITE sATERENTITALS sATERENTITALS INTERELITATINT构成组成。适当的大气映射可能会消除空气衍生的空间PNT系统中的错误错误。第一个研究目标是扩展PNT卫星的算法和数据处理框架，称为大气映射和卫星完整性监测系统（AMSIM）。该研究将适应系统的实际限制，包括光谱和轨道配置​​。第二个研究目标是证明轨道上Amsim的主要要素，这将通过低地球轨道中的两个示范卫星来完成。第三个研究目标是结合这些因素，以告知生产系统的真正PNT性能，以便可以清楚地将其传达给目标最终用户。预期的技术结果将是一个在商业上可行且技术上可行的空间系统体系结构，可以实现精确的全球PNT系统，该系统可以提供10厘米和1纳秒的准确性。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子和更广泛的影响来评估NSF的法定任务，并被视为珍贵的支持。
