Satellite Workload Offloading by Land and Water Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional satellite workload management techniques fail to efficiently utilize satellite processing capabilities due to the lack of consideration for orbital movements with respect to geographical landmarks like land and bodies of water, resulting in inefficient workload allocation as satellites often pass over areas with no target devices.
Innovation Solution
A method that generates a temporal mapping of satellite positions relative to land and water bodies, determining job offloading based on proximity to land, and enabling satellites to offload jobs to other satellites when over water, optimizing computational processing by leveraging idle time and satellite mesh communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If satellites continuously process workloads regardless of position, then processing capacity is maximized, but energy is wasted when satellites are over water with no target devices
Solution Approach 1:
The satellite workload management system dynamically adjusts processing operations based on real-time positional information. The system determines whether the satellite is over land or water and adaptively modifies workload execution accordingly, transitioning from static continuous processing to dynamic position-aware processing that optimizes both productivity and energy efficiency
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring satellite positional data and using this information to control workload processing decisions. The positional feedback loop enables the system to recognize when the satellite is over water and automatically adjust operations to prevent energy waste, while maintaining high productivity when over land
2Productivity
If satellites offload jobs frequently to maintain optimal positioning, then workload allocation efficiency improves, but system complexity increases
Solution Approach 1:
The workload management system is segmented into distinct functional modules: positional determination module, workload evaluation module, and offloading control module. This segmentation allows each component to perform its specific function independently, simplifying the overall system architecture while maintaining high allocation efficiency through coordinated operation of these modular components
Solution Approach 2:
The patent introduces an intermediary workload management system that acts as a mediator between the satellite's processing capabilities and the ground-based target devices. This intermediary layer intelligently determines when offloading is necessary based on positional information, reducing the need for complex direct satellite-to-device coordination protocols
3Speed
If satellites process all workloads locally, then response time is minimized, but computational resources are underutilized during water coverage periods
Solution Approach 1:
The system performs preliminary evaluation of workload characteristics and satellite positional information before executing processing decisions. By pre-assessing whether the satellite is in a high-utilization zone (over land) or low-utilization zone (over water), the system can proactively determine optimal offloading时机, ensuring both rapid response when needed and efficient resource utilization

AI summary
A computer-implemented method, according to one embodiment, includes generating a temporal mapping of positions of a first satellite with respect to predetermined portions of land of Earth and predetermined bodies of water of the Earth. The method further includes determining, based on the temporal mapping, a first job for the first satellite to offload to a first target device during a first period of time that a footprint coverage region of the first satellite is within a predetermined proximity to a first of the bodies of water. In response to a determination that the footprint coverage region of the first satellite is within the predetermined proximity to the first body of water, the first satellite is caused to offload the first job to the first target device.
