Methodology for quantitatively evaluating satellite communication network survivability

A methodology is proposed to measure the electronic and physical survivability of satellite communications as a function of system architecture, the cost to the enemy to destroy the network (C sub E); the cost to the communicator to implement the network (C sub C); and the rate of throughput. It is shown that the rate of change of network survivability can be obtained as a function of C sub E/C sub C. The methodology is applicable to the evaluation of: realistic jamming threats; the jamming survivability of satellite communications systems; and the physical survivability of the ground and space segments in communications networks.
