Abstract:

Network emulation on Starlink constellation is an important verification and evaluation tool for the design and construction of low earth orbit constellations in the future. Aiming at the characteristics of large-scale and complex structure of the Starlink network, a high-performance satellite network emulation system is designed. Based on the distributed network emulation architecture of cloud platform, through the development of STK Engine underlying interface, satellite model library storage optimization and asynchronous message transmission technology, the rapid deployment of Starlink constellation is carried out, and has good scalability. The experimental results show that the proposed method can carry out the automated modeling of a complex satellite network of 400 satellites. Compared with the traditional method, the deployment efficiency is improved by 39.07%. The method is an emulation technical support for the construction of large-scale low earth orbit satellites.

Key words: Starlink, low earth orbit constellation, network emulation, cloud platform, rapid deployment
