Benchmarking against real data

Definition

Benchmarking against real data refers to the process of comparing simulated or modeled results of space debris scenarios with actual observed data from space. This practice is crucial for validating models and ensuring that the predictions made by simulations are accurate and reliable. By using real-world data, researchers can refine their models, enhance their understanding of debris behavior, and improve mitigation strategies for space debris management.
