System

Analysis Description

The thermal model was developed to simulate the in-orbit thermal behavior of MDS-1. The model consists of 597 nodes (bus system: 533 nodes, payloads: 64 nodes). The developed model presented that the difference between the analysis results and the measurement data is within 5°C for most equipment.
