Satellite communication is one of the most popular next generation communication technologies for global communication networks in parallel to terrestrial communication networks. In modern age military intelligence, navigation & positioning, weather forecasting, digital video Broadcasting (DVB), and broadband internet services, are the few demanding applications of Satellite communication. Alth...

In this article, design and analysis of an optimal orbit control for a communication satellite is investigated. It is the challenging task and critical importance to control the orbit of a communication satellite especially the one used for worldwide communication. The main objective of this work is to evolve a design based on modelling and simulation of an optimal orbit controller for a satell...

A satellite communications system is based on antennas in a stable orbit above the earth. Satellites serve as relay stations in the sky. The basic idea of satellite communications is that two stations on earth discuss via one or more satellites. So a little bit of satellite-related terminology: 1. Earth station is an antenna on or near the surface of the earth. 2. Uplink is a transmission from ...

This paper describes the essential segments of a satellite based communication and asset management system. The Low Earth Orbit satellite used for such a system is the ORBCOMM low earth orbit (LEO) constellation. The architecture and network structure of the satellite system is described. The satellites themselves are very small and are launched using the Pegasus launch vehicle. This makes the ...

in this paper satellite wave propagation at ku and ka band is considered. the design and simulation of a typical satellite beacon receiver at ka band is designed and simulated for the future works. also rain attenuation prediction at ku band using satellite signal beacon measurement and simulations for iran telecommunication research center (itrc) are presented. the measurement setup consists o...

In this paper we study about optical and millimeter radio wave cross-link for formation flight communication satellite system in a geostationary orbit. In formation flight system, since the distance among the satellites becomes short compared with the conventional inter satellite communication link, the size and the weight of the communication system can be reduced. If the high data rate cross-...

Communication in the whole of the World is revolutionized with the advent of Satellites. Satellite Communication has served mankind in many ways e.g. to predict weather, storm warning, provide wide range of communication services in the field of relaying television programs, digital data for a multitudes of business services and most recent in telephony and mobile communication. It may not surp...
