KR-20260065999-A - Blockchain-Based Management System and Method for LEO Satellite Orbital Occupancy and Traffic Rights

Abstract

The present invention relates to a system and method for assetizing the flight path of a low-orbit satellite as a three-dimensional cylindrical space corridor and managing it using blockchain-based traffic tokens. The system according to the present invention includes a traffic corridor database, a token management module, a proof-of-occupancy unit, a traffic management smart contract unit, and a ranking management module. It realizes an efficient and economical space traffic management system by combining Proof-of-Occupancy technology, which verifies actual path occupancy in real time by analyzing satellite telemetry, and Smart Contract technology, which fully automates path yielding and compensation via traffic tokens in the event of a collision risk. Through this, it is possible to maximize the economic efficiency of orbital resources, prevent collision accidents, and create a new space financial ecosystem.

Description

Blockchain-Based Management System and Method for LEO Satellite Orbital Occupancy and Traffic Rights Blockchain-Based Management System and Method for LEO Satellite Orbital Occupancy and Traffic Rights The present invention relates to the operation management of Low Earth Orbit (LEO) satellites and blockchain-based digital asset trading technology. More specifically, it relates to space traffic management technology that compartmentalizes optimal flight paths in a dense satellite orbit environment into three-dimensional cylindrical spatial units to monetize them as traffic tokens on a blockchain, and automates path yielding and compensation transactions through a smart contract when a collision risk occurs between satellites based on real-time Proof-of-Occupancy (PoO) through satellite telemetry data. Recently, due to the rapid expansion of satellite constellation services such as Starlink, OneWeb, and Amazon Kuiper, the density of satellites in low Earth orbit (LEO) is increasing from hundreds to tens of thousands. According to statistics from the International Telecommunication Union (ITU), the number of licensed satellites in the LEO region is expected to exceed tens of thousands within a few years, and consequently, the risk of collisions between satellites and the competition for paths in specific combinations of altitude and inclination angles are intensifying. Current Space Traffic Management (STM) systems are predominantly based on relying on centralized tracking data from ground control stations or performing Collision Avoidance Maneuvers (CAM) based on the independent judgment of individual satellite operators. However, this approach has the following structural limitations. First, the absence of an objective compensation system for fuel loss and mission downtime resulting from orbital corrections leads to structural unfairness, where satellite operators who perform evasive maneuvers first must bear the economic disadvantage. Second, despite fierce competition to secure specific optimal corridors, the lack of a legal and technical framework to formally monetize and trade these routes creates a high potential for international disputes. Third, the existing method, which relies on negotiations between satellite operators, is slow, potentially delaying responses in situations where collision risks unfold in real time. Blockchain technology guarantees data integrity and transparency through a distributed ledger and features the ability to automatically execute transactions via smart contracts when pre-agreed conditions are met. When applied to space traffic management, this allows for market-based allocation by tokenizing route ownership rights and overcomes the limitations of existing centralized management by enabling immediate and automated compensation transactions in the event of collision risks. However, conventional technology lacks any guidance on a specific and integrated system that combines real-time ownership proof utilizing telemetry data with a blockchain reward mechanism.
