The core technology behind 6G, AI, autonomous driving, and maritime logistics is Low Earth Orbit (LEO) satellite communication technology. In an era of rapidly increasing data traffic, conventional geostationary orbit (GEO) satellites are becoming increasingly unable to meet industrial demand due to transmission delays and limited processing capacity. As a solution to these limitations, LEO satellite communication systems are emerging.

Conventional satellite communication has mainly relied on geostationary orbit (GEO) satellites positioned at an altitude of approximately 36,000 km. However, these systems have faced issues such as long signal delays caused by the high altitude, high launch costs, and limited coverage. In contrast, LEO satellite communication systems place satellites at relatively low altitudes of 200 km to 2,000 km above the Earth, enabling faster response speeds and lower latency. In addition, launch and operating costs are relatively low, making it possible to establish global coverage through a “Mega Constellation” structure in which thousands of satellites are operated simultaneously.
The core of LEO satellite communication technology is the ability to provide both high speed and wide coverage. Thousands of satellites continuously move while densely covering the entire Earth, and AI-based optimization algorithms efficiently coordinate inter-satellite communication and connections with ground stations. In addition, laser links between satellites, or optical communication technology, minimize communication latency and enable seamless connectivity even in areas without terrestrial base station infrastructure.
Global companies are already entering this field on a large scale. SpaceX currently operates more than 5,000 LEO satellites through its Starlink project, while Amazon is pursuing the construction of a satellite network consisting of more than 3,000 satellites through Project Kuiper. Global shipping companies such as Maersk and MSC are also developing logistics optimization systems linked with LEO-based satellite networks to overcome the limitations of maritime logistics communication networks. These companies expect low-latency communication networks to become critical infrastructure for autonomous ships and global logistics in the future.

In Korea, Spacebit Co., Ltd. (CEO: Jungtae Park) is working to internalize core technologies in the field of LEO satellite communications. Spacebit recently completed successful ground testing of a relay-type AOWC (Adaptive Optical Wireless Communication) system jointly developed with ETRI (Electronics and Telecommunications Research Institute, Honam Research Center). This is an ultra-high-speed, highly reliable, and highly secure communication technology capable of achieving speeds up to 1,000 times faster than conventional RF and TCP/IP methods without data loss. The technology can be applied to various fields, including LEO communication satellites, space exploration spacecraft, and military communication systems, and is attracting attention as a key capability that could enable Korea to achieve technological independence and sovereignty in the global space internet market.

When developing LEO satellite communication-based space internet technologies, a systematic and proactive strategy for intellectual property (IP) protection is essential. In particular, technologies such as ultra-high-speed transmission and reception, inter-satellite optical communication, frequency interference avoidance algorithms, and satellite-ground integration modules each possess technical independence and competitiveness. Therefore, multiple layers of protection should be established by subdividing technologies according to function and pursuing divisional and continuation patent applications. In addition, core communication protocols such as AOWC should not be claimed merely as technologies for improving transmission speed. Instead, claims should be structured based on “ultra-high-speed, lossless, and highly secure” configuration-operation-effect relationships, thereby clearly protecting real-time data processing performance within satellite networks, disaster response capabilities, and compatibility with international communication protocols.
At the same time, FTO (Freedom to Operate) analysis based on published patents and international patent databases of global leading companies such as Starlink and OneWeb is essential. If technological similarities are identified in optical communication or inter-satellite connectivity technologies, companies should establish legal protection against competitors through design-around strategies that differentiate algorithm structures or intended uses, or through blocking patents. In addition, if actual communication modules are operated in the form of a SaaS platform, software patents and copyright registrations should be pursued in parallel for technologies such as ground control systems, telemetry UIs, and automated optimization processing logic in order to broaden the scope of protection.
Comprehensive patent design that considers future scalability should also be pursued. LEO-based communication technology can be applied not only to space internet services but also to numerous high-reliability network applications, including autonomous driving, maritime logistics, disaster communications, and military secure communications. Therefore, platform-oriented patents should be designed from the initial stage with expansion into multiple industries in mind. In addition, compliance issues related to international communication regulations such as ITU standards, cybersecurity guidelines, and satellite radio interference criteria should be reflected in patent specifications and claim structures in order to minimize legal risks when entering global markets.
The BLT Research Center stated, “Low Earth Orbit satellite communication technology is expected to create new opportunities for companies.” It added, “Securing rights to various technologies related to LEO satellite communications is expected to be an effective strategy.”
As of 2025, BLT Patent & Law Firm has been selected by more than 2,000 innovative startups as a partner, supporting corporate growth and success through IP acquisition, response strategy development, investment attraction, and IP-based business support such as technology-specialized listings.
