Nanjing Intane Optical Engineering Co., Ltd. was founded in 2003 by Professor Zhou Bifang, former director of the Nanjing Astronomical Instruments Research Center of the Chinese Academy of Sciences and a doctoral supervisor. It is a national high-tech enterprise with precision optical system solutions as its core competitiveness, focusing on the R&D and provision of satellite laser communication systems and related products. The company was listed on the New Third Board in 2016 (stock code: 836787). It is a national-level specialized and sophisticated "little giant" enterprise, has passed ISO9001 quality management system certification and work safety standardization certification, and holds the qualification of a weapons and equipment manufacturing unit. The company has three provincial-level R&D platforms (Jiangsu Provincial Engineering Technology Research Center, Jiangsu Provincial Engineering Research Center, and Jiangsu Provincial Enterprise Technology Center) and a provincial-level academician workstation. It has been recognized as a Jiangsu Provincial Innovation and Entrepreneurship Team and a Nanjing Intellectual Property Demonstration Enterprise. To date, it has obtained more than 80 authorized patents (including more than 40 invention patents), established industry-university-research cooperation with many universities such as Nanjing University, Nanjing University of Aeronautics and Astronautics, and Nanjing University of Science and Technology, and has two provincial-level graduate workstations. Relying on more than 20 years of accumulated capabilities in complex system design, integration, testing, and key component manufacturing, the company has built an R&D team mainly focused on optical engineering and space optical communication, and has made outstanding contributions to major national scientific research projects such as the "Chang'e Project," the "Tianwen Mars Exploration Program," the "Zhurong Rover," and "Shenzhou-12." Since 2005, the company has continuously participated in national satellite laser communication technology research. It has successively completed the independent development of five generations of space-based terminals, five generations of ground-based terminals, and two generations of air-based laser communication terminals. It has won the Jiangsu Provincial Science and Technology Award and undertaken Nanjing's first batch of major science and technology projects and Jiangsu Provincial Scientific and Technological Achievement Transformation Projects. In 2011, the company's technology helped the "Haiyang-2" satellite achieve China's first two-way laser communication between a low-orbit satellite and the ground. The related achievements won the Special Prize of the National Defense Technology Invention Award and the First Prize of the National Technology Invention Award. In 2017, it supported the "Shijian-13" satellite in completing 5 Gbps high-speed satellite-to-ground laser communication verification in geosynchronous orbit. In 2020, its independently developed micro-nano satellite laser communication payload successfully completed in-orbit verification, filling a domestic technological gap. In 2025, the inter-satellite laser communication terminal developed by the company for the GW constellation was successfully launched and carried out in-orbit verification. As one of the earlier enterprises participating in the formulation of technical standards for laser communication terminals of China Satellite Network Group, the company won first place in the first public bidding for inter-satellite laser terminals in 2023 and passed prototype system acceptance in the same year. In 2024, the Innovation Research Institute of China Satellite Network Group sent a special letter of thanks, recognizing the company's technical contributions and recommending it to participate in the planning and construction of the laser communication terminal production line at the Hainan Wenchang Satellite Super Factory. In 2025, the company undertook the verification task for the inter-satellite laser link of the second-generation GW constellation satellites. It is a private commercial aerospace enterprise with deep technological accumulation and rich engineering experience in China. At present, the construction of global satellite internet is accelerating, and commercial aerospace has been included in the catalog of national strategic emerging industries and has become the first of the top ten fields of new quality productive forces. Intane Optics will keep pace with the national satellite internet construction, implement the innovation-driven development strategy, and contribute to the construction of China's version of "Starlink" and to space information security.
