Introduction

The whole low-orbit satellite modelling is based on published data from Telesat, Canada. Based on a summarization from MIT.

Methodology

1. Execute linkage_budget.m where you can get the whole constellation and earth stations，the code will calculate linkage budget and get mapping matrix from three different dimensions.

2. Execute more_linkage_budget.m where you can get linkage budget of mutable targets like vehicles, aerocrafts, ships and missiles.

3. Execute select_modulation.m where you can recify the mode of modulation/demodulation.

4. Execute concatenate.m where you can get real time LLA information, a critical parameter in antenna gain calculation.

5. Execute graph3.m where you can get global antenna gain.

6. Execute acc.m where you can get visible analysis.
