Free-Placement Optimization of Ground Station Locations for Low-Earth Orbit Satellites
TL;DR
As low Earth orbit satellite constellations grow, existing ground station designs struggle to meet increasing demands. SCORE (Sequential Cyclic Optimization via Refinement & Evaluation) is a new method that optimizes ground station locations over a continuous spatial domain.
✦ Why It Matters
Engineers can leverage SCORE to optimize ground station placements, enhancing satellite communication efficiency.
Key Takeaways
- Implement SCORE for flexible ground station placement.
- Expect up to 13% improvement in downlink throughput.
- Reduce function evaluations by up to 5x compared to traditional methods.
- Evaluate trade-offs between new site deployment and existing station expansion.
How It Works
SCORE operates in two stages: first, it selects coordinates for potential ground station locations, and then it refines these selections through cyclic optimization. This approach allows it to explore a broader spatial domain, overcoming limitations of traditional fixed-site methods and enhancing overall performance.
