This Small Business Innovation Research (SBIR) Phase I project seeks to deploy a commercial space platform in cislunar and deep space to provide fast connectivity, navigation, and positioning to space users. This cislunar network will include nodes in low-Earth Orbit, Geosynchronous orbit and Lunar orbit to create a secure and covert gigabit network for scientific, commercial, and military applications. This project will develop a revolutionary spacecraft that will be the heart of the new network. This product will be a small yet nimble spacecraft that uses lasers, a novel architecture, and machine learning software to provide high-data-rate omnidirectional coverage of its surroundings. The company plans to place clusters of this satellite as network nodes. It is envisioned that space users can use these interplanetary small satellites (and their network) for gigabit connectivity as well as accurate navigation and positioning in cislunar and deep space.This project will develop a novel small satellite with embedded optical communications systems. It will be equipped with two distinct optical communications terminals, one for long-range connectivity and the second one for short-range, swarm connectivity. The small satellite’s long-range terminal consists of six optical transceivers evenly distributed around the body of the spacecraft to provide omnidirectional coverage. The transceivers will be fully integrated into and commanded by a fast processor. The small satellite will have a coherent modulation architecture operating at around 1550 nanometers. The transmitter design to be pursued during this project includes a distributed feedback laser diode, a phase modulator, an optical amplifier, a circulator, and a collimator. All these components will be connected by optical fibers. The seed laser will produce a 10-milliwatt laser beam, which is passed through the phase modulator where it is modulated at high speeds (10-100 gigabit per second). After the modulator, the modulated beam is boosted via an optical amplifier and passed through a collimator to generate a collimated, high-power beam. The collimator launches the beam into free space and directs it to a steering mirror for coverage of its field of regard. It is envisioned that the system could achieve transmission speeds as high as 100 gigabit per second.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）I阶段项目旨在在Cislunar和Deep Space部署商业空间平台，以向太空用户提供快速的连通性，导航和定位。该Cislunar网络将包括低地球轨道，地球同步轨道和月球轨道的节点，以创建一个安全且覆盖的千兆网络，用于科学，商业和军事应用。该项目将发展一个革命性的航天器，该产品将是一个小而灵活的航天器，它使用激光器，一种新型的建筑和机器学习软件来提供对周围环境的高数据速率的全向覆盖范围。该公司计划将该卫星的簇作为网络节点。可以预见的是，太空用户可以使用这些星际小卫星（及其网络）进行千兆连接性，以及在Cislunar和Deep Space中的准确导航和定位。此项目将开发一个具有嵌入式光学通信系统的新型小型卫星。它将配备两个不同的光学通信终端，一个用于远程连接，第二个用于短期连接。小卫星的远程末端由六个光学收发器均匀分布在航天器体内，以提供全向覆盖范围。收发器将由快速处理器完全集成并指挥。小型卫星将具有约1550纳米的连贯调制体系结构。在此项目期间要进行的发射器设计包括分布式反馈激光二极管，相调节器，光学放大器，电路和准直仪。所有这些组件将通过光纤连接。种子激光器将产生10毫米的激光束，该光束通过相调节器以高速调节（每秒10-100千兆位）进行调节。调制器后，通过光学放大器来增强调制光束并通过准直仪以生成过时的高功率梁。直接仪将光束发射到自由空间中，并将其引导到转向镜上，以覆盖其关注领域。可以预见的是，该系统可以达到每秒100千兆位的传输速度。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响标准，被视为通过评估而被视为珍贵的支持。
