Satellites
The Meaning of Satellite
A satellite is an object that orbits or moves round another object. Satellites may be natural (such as planets and moons) or artificial such as the communication satellite (COMSAT). A satellite is communication equipment which is deployed and stationed in the space to send signals to different countries of the world. Satellites are systems of global transmission of signals from one place to another. With the satellite, it is now possible for live telecast of an event in Lagos to be viewed in America, e. g. an international football match. Satellite enhances the work of NITEL as messages are sent and received in many countries of the world, especially those that are members of International Satellite Communication.
