Automated Resource Allocation for Satellite Observation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite-based observation systems face challenges in efficiently allocating resources for simultaneous observation of multiple regions of interest, leading to conflicts and inefficiencies, especially when using manual allocation methods.
Innovation Solution
An automated resource allocation system that assigns mobile sensor carrier platforms to operate in three modes: static observation, dynamic tracking, and signal emission/reception, based on criteria such as relative position, movement direction, line of sight, and available resources, to optimize task allocation and system flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual resource allocation is used for satellite-based observation, then flexibility in task assignment is improved, but resource conflicts and inefficiencies increase when observing multiple regions of interest simultaneously
Solution Approach 1:
The resource allocation unit automatically assigns sensor carrier platforms to observation tasks based on real-time criteria evaluation, enabling the system to self-manage resource allocation without manual intervention. This resolves the contradiction by maintaining flexibility through automated decision-making while improving efficiency through systematic resource management
Solution Approach 2:
The system continuously evaluates multiple criteria including relative position, direction of movement, line of sight, and available resources to dynamically adjust task assignments. This feedback mechanism allows the system to adapt to changing conditions while optimizing resource utilization across multiple simultaneous observation tasks
2Area of stationary object
If multiple sensor carrier platforms are used for simultaneous observation of multiple regions of interest, then observation coverage is improved, but resource conflicts increase
Solution Approach 1:
The system divides observation tasks and sensor carrier platforms into distinct groups, with the resource allocation unit assigning specific platforms to specific regions of interest based on real-time criteria. This segmentation prevents resource conflicts by ensuring each platform has a dedicated observation mandate while maintaining overall system coverage
Solution Approach 2:
The resource allocation unit dynamically reassigns sensor carrier platforms to different observation tasks based on changing conditions such as relative position, movement direction, and line of sight availability. This dynamic allocation allows the system to maintain optimal observation coverage while preventing resource conflicts through continuous adaptation
3Adaptability or versatility
If satellite sensor carrier platforms are continuously moved to observe different regions, then observation flexibility is improved, but measurement precision decreases due to changing relative positions
Solution Approach 1:
The resource allocation unit evaluates the predicted future position and movement direction of sensor carrier platforms before assigning observation tasks. This preliminary assessment ensures that platforms are assigned to tasks where they will maintain optimal observation geometry, thereby preserving measurement precision while retaining observation flexibility
Solution Approach 2:
The system changes the assignment parameters dynamically, considering not only current position but also predicted movement trajectory, line of sight duration, and relative velocity. By adjusting these parameters, the system maintains observation flexibility while ensuring that measurement precision requirements are met through careful task-platform matching
