Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite systems face challenges in maintaining accurate geometry and relative positions between satellites, which limits their ability to adapt to changing conditions and reduces data transmission efficiency due to interference.
Innovation Solution
A multi-satellite system with at least three satellites in co-orbital formation, equipped with propulsion systems and control systems that dynamically change the configuration and shape of the satellite formation by controlling the relative distances and directions between antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If satellites maintain fixed geometry and relative positions in formation, then system stability is improved, but adaptability to changing conditions deteriorates
Solution Approach 1:
The patent implements dynamic reconfiguration capability where satellites can change their relative positions and formation geometry in real-time. The system transitions from static fixed-geometry formations to dynamic reconfigurable formations, allowing satellites to adjust their configuration based on changing operational requirements while maintaining stability through controlled transitions.
2Device complexity
If satellites use fixed antenna configurations, then device complexity is reduced, but beam steering capability and tracking performance deteriorate
Solution Approach 1:
The patent implements electronically steerable antenna arrays that can dynamically change beam direction without mechanical movement. The antenna configuration transitions from fixed physical orientation to dynamically reconfigurable electromagnetic beam steering, enabling rapid tracking of moving objects and efficient data transmission while maintaining relatively simple antenna hardware.

AI summary
The technology disclosed relates to a multi-satellite system including at least three satellites where at least two of the satellites comprises at least one antenna array for obtaining observation data, and methods for controlling and continuously changing the configuration of a multi-satellite formation including at least three satellites in a formation. The system enables controlling the relative distances between the satellites and continuously changing the configuration and directions of antenna arrays of separate satellites in a multi-satellite formation in that at least one of the satellites comprises a propulsion system for continuously changing the movement and direction of the satellite relative the other satellites in the formation to thereby, in turn, also change the relative distances and directions between the antennas of separate satellites in the formation.
