With the deepening of the research on Space-Sky information network, its application has also become popular, higher requirements are imposed on the invulnerability of Space-Sky information network. Combined with the current research status of research on the invulnerability of the Space-Sky information network, the first is an overview of the Space-Sky information network and its most representative Walker constellation. Secondly, the general methods of research on the invulnerability of Space-Sky information network is investigated. Then the concepts of “probability matrix” and “natural connectivity” are given, and the invulnerability optimization method of Walker constellation is derived. Finally, co-simulation is performed by STK and MATLAB according to the optimization method. The invulnerability of Walker constellation was evaluated with the changes of orbital inclination and orbital altitude.
