The International communications satellites that have been launched since have shown the effectiveness of the satellite system. However, the use of satellites for communication and data transfer also extend beyond the parameters of the earth.
This paper will examine various aspect of satellite communication with Mars. The following discussion will therefore deal with the various architectures, protocols and methods of data transference that are necessary in order to facilitate satellite communication between Earth and Mars. This discussion will also deal worth the envisaged IPN or Interplanetary network and the data and relay requirements that are needed to deal with the demands and problematics of satellite communication and data sharing between planets.
Brief Overview and background In essence a communication satellite is essentially a relay station that can be Term paper on satellite communication to provide for the transfer of data and information. Put rather simplistically, "A communications satellite is a radio relay station in orbit above the earth that receives, amplifies, and redirects analog and digital signals carried on a specific radio frequency" Satellite Basics: Guide To Satellite-based Solutions.
It is also important to note that they have many other uses besides communication. Furthermore, scientific studies of our planet, the atmosphere and the universe all rely on satellites.
At its most fundamental, satellite communications have two main components. The first is the satellite itself, also known as the space segment. This is comprised of three distinct units; namely, the fuel system, the satellite and telemetry controls, and the transponder.
The transponder includes the following elements: The second aspect of conventional satellite communication is the Ground Station or the earth segment. This Ground Station has a double function which is to act as an uplink to transmit data.
This is usually in the form of baseband signals which are passed through a baseband processor, via an amplifier and through a parabolic dish antenna up to the orbiting satellite Satellite Communication.
However, as will be discussed in the following sections, this situation becomes much more complex and convoluted when communicating via satellite with Mars. There are also other fundamental aspects so satellite communication that could be noted and that have reference to the topic of This paper.
For instance, an important characteristic of satellite systems is that they can be implemented so as provide two basic types of circuits: This is a factor that is relevant when it comes to the architecture of communication with satellites in deep space.
This is similar to the mode of transfer in cable and microwave circuits. These circuits are more flexible in terms of data routing. In terms of the present study the advances in satellite and communications technology has meant that it has now become possible to launch and communicate with artificial satellites in orbits round the other planets.
This refers especially to satellite communication with Mars. However, the situation with regard to space communication at this level of complexity presents a number of different criteria that have to be considered in terms of communication.
This is due to factors such as distance and line of sight - which is the fact that obstacles to a signal transmission and its reception can prevent communication. Another fact that needs to be considered in terms of space communication is weight - which refers to the fast that the high-powered sensors and antenna needed in space are often too heavy for practical purposes and transportation.
Usually satellites have between 24 and 72 transponders. A single transponder is capable of handling up to million bits of information per second Satellite Basics: This transfer of information is facilitated within radio frequency bands.
The frequency bands most used by satellite communications companies are called C-band and the higher Ku-band. The architecture of satellite usage and transmission in terms of communicating in space and between Earth and other planets is based on the principle of providing reusable and sharable physical infrastructures which are intended to accommodate the communication needs of various space missions.
The necessary architecture is furthermore intended to link network assets in terms three zones; namely earth, orbiting and deep space Tahboub and Khan.
An important aspect of the theory of this architecture is that, Space protocol architectures will transparently provide end-to-end communication services to space networks. These architectures also describe the design of the protocol suite applied by all assets such as satellites, rovers, and scientific equipments deployed in the space network.
Tahboub and Khan Furthermore, this architecture should be interoperable with standard terrestrial communication protocols, enabling both secured and real-time Internet-based access to on-going space missions.
In the light of this outline and considering satellite communication with Mars, there are a number of challenges that have to be considered with regard to the architecture.
These include aspects such as long propagation delays, network mobility, link intermittency, limited resource allocationextreme reliability and security Tahboub and Khan.The Federal Communications Commission regulates interstate and international communications by radio, television, wire, satellite and cable in all 50 states, the District of Columbia and U.S.
