LEO Constellation Datacenter With Laser Transfer for Geo-Restricted Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems in Low Earth Orbit (LEO) satellite constellations face challenges in securely storing geo-location restricted data due to latency issues and the need to comply with data residency and sovereignty regulations, which require data to be stored within specific geographic boundaries.
Innovation Solution
A LEO satellite constellation datacenter defines a geo-location cone extending from a given geographic location boundary, ensuring geo-location restricted data is stored within this cone by transferring it between LEO satellites using laser-based data transfer and implementing multi-factor authentication with blockchain for secure data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data is stored in geostationary satellite, then data storage is achieved, but latency increases
Solution Approach 1:
The patent segments the data storage function across multiple LEO satellites in a constellation rather than relying on a single GEO satellite. This allows data to be distributed and accessed from multiple locations, reducing the effective latency by eliminating the high orbital distance of GEO satellites while maintaining continuous availability through the constellation architecture.
2Loss of time
If LEO satellites are used for data storage, then latency is reduced, but data residency compliance becomes difficult due to satellite movement
Solution Approach 1:
The patent implements a dynamic data management system that continuously tracks satellite positions and proactively transfers data between satellites before they exit the geo-location cone. This dynamic approach maintains data residency compliance despite satellite movement, unlike static storage solutions that would fail to meet geo-restriction requirements.
Solution Approach 2:
The system performs preliminary data transfer operations by identifying when a satellite is approaching the boundary of the geo-location cone and transferring data to a satellite that will remain within the cone. This proactive measure ensures continuous compliance with data residency requirements without interruption, preventing the compliance violation that would occur with reactive or static approaches.
3Reliability
If data is transferred between satellites, then geo-location compliance is maintained, but system complexity increases
Solution Approach 1:
The patent creates a universal data management platform that handles multiple functions: data storage, position tracking, compliance monitoring, and automated data transfer. This multi-functional system reduces overall complexity by consolidating what would otherwise require separate specialized systems for each function, making the complex operations manageable through a unified approach.

AI summary
Disclosed embodiments provide systems and methods for implementing enhanced geo-restricted data management in satellite constellation datacenters. A disclosed system and methods implement a satellite constellation datacenter of multiple LEO satellites that enables real-time satellite communications using lasers and secure data storage in the satellite constellation datacenter to protect critical data from unauthorized access and supports secure data transfer between the LEO satellites using laser based data transfer. To enable secure storage of geo-location restricted data in a LEO satellite, the LEO satellite constellation datacenter defines a geo-location cone and requires that the geo-location restricted data be stored within the geo-location cone. LEO satellites within the defined geo-location cone store the geo-location restricted data and securely transfer the geo-location restricted data from one satellite to another satellite within the defined geo-location cone.
