Satellite Constellation Orbital Plane Layout for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite constellations with multiple orbital planes at the same altitude, there is a risk of collisions between satellites due to similar ground speeds and overlapping service areas, increasing as the number of satellites and planes increases.
Innovation Solution
A satellite constellation forming system that creates multiple orbital planes with distinct altitudes to prevent collisions by ensuring satellites in the same plane maintain relative phases and fly at different altitudes, using a satellite constellation forming unit to set and maintain these altitudes.

Engineering Contradiction Analysis
1Quantity of substance
If multiple orbital planes are used to increase satellite constellation capacity, then the number of satellites and service coverage are improved, but collision risk increases due to satellites flying at the same orbital altitude
Solution Approach 1:
The patent applies dimensionality change by transitioning from a two-dimensional arrangement (multiple orbital planes at the same altitude) to a three-dimensional arrangement (orbital planes at different altitudes). This vertical stratification in the altitude dimension allows for increased satellite capacity while maintaining collision avoidance through spatial separation.
2Duration of action of moving object
If satellites are arranged at the same orbital altitude for efficient service coverage, then service continuity is improved, but collision risk increases due to overlapping service areas and similar ground speeds
Solution Approach 1:
The patent applies local quality by assigning different altitudes to different orbital planes, creating localized variations in the orbital parameters. This allows each orbital plane to maintain its service continuity characteristics while the overall constellation benefits from reduced collision risk through altitude differentiation.

AI summary
A satellite constellation forming system forms a satellite constellation. The satellite constellation is composed of a satellite group. In the satellite constellation, the satellite group provides a service cooperatively. The satellite constellation has a plurality of orbital planes in which a plurality of satellites fly at the same orbital altitude in each orbital plane. A satellite constellation forming unit forms the satellite constellation in which orbital altitudes of the plurality of orbital planes are mutually different.
