In general, the terrestrial communication resources are limited when infra structure is damaged or excessive traffic. But it is essentially required that an emergency communications should be reliable and flexible for disaster mitigation and relief operation. All users wish emergency communications is working perfectly everywhere and every time in any circumstances. Moreover the need for broadband communications during disaster or emergency times is gradually increasing recently. Based upon radio links, satellite based systems have several advantages in terms of reliable, available, robust, quickly deployable, and accessible from any locations. In this paper a satellite communications system is introduced as a core network for emergency management and disaster recovery including satellite network topologies, service configuration, and recommended technical specifications.
