The skywave propagation is suitable for radio waves of frequency a from 2 MHz to 50 b upto 2MHz c from 2.

. List a few common application areas for each orbit level satellite system. It requires focused signals and line of sight as physical path. Calculate the signal strength at the receiver.

In active satellite the satellite receives a fraction of energy beamed toward it. Fiber optic cables are more fragile when compared to copper wires. Microwave Satellite Fiber Optic and Internet IP Transmission I t does little good to have a great news story or program segment if you cant transmit it back to a local station cable news outlet or network to broadcast.

The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. It is an expensive technology. Explain about the optical sources.

Such connections allow the devices to share and exchange information. Explain the block diagram of an optical. Fiber optic system is immune to electrical interferences.

The control can be affected by the satellite itself and from the ground. The most frequently used in the process industries are the star the bus and the ring network systemsBut we need a transmission media for that lets looks in to the Difference between Twisted PairFiber Optic and Coaxial cables. No cable splices Light source to fiber interface loss of i 9 dB in satellite 16 Fiber to light defector loss of 2.

C Fiber optic cables. Coverage area of a satellite based system is greater than that of a terrestrial based wireless communication system. Satellite systems are in service or have been proposed for each of the other services.

Difference between Satellite System and Terrestrial System. In this module we will cover a variety of point-to-point video and audio transmission approaches. _____ is a fast-growing technology in the field communication system.

Fiber optic cables are cheaper than copper cables. In satellite microwave transmission system the installation of satellites is extremely tough. Attitude and orbit control system is used to control the orbit of the satellite besides helping to maintain stabilization and its position.

An alternative to damaged fiber-optic networks for disaster recovery options Multipoint-to-multipoint communications facilitated by the Internet and broadcasting capability of satellites During the next millennium wireless satellite systems will play a significant role in meeting telecommunication needs. 3 SATTELITE SYSTEM CHAPTER 1 11 Introduction-Satellites offer a number of features not readily available with other means of communications. With a neat sketch for a ray propagation into and down an optical fiber cable derive an expression for the acceptance angle.

Couch II William J. In the passive satellite system the ground transmitting system beams power at the reflector. Email telephone networks spying remote sensing video conferencing.

Derive satellite system link equation. Learn about satellite communication its advantages active and Satellite communication is part of telecommunication which builds a link between different parts of the earth and involves satellite. The present consensus is that satellite communications systems should be established in harmony with terrestrial systems such as optical fiber as a foundation for the information and communications society of the 21st century.

Microwave communications are ideal for television and radio broadcasts while satellite communications are used for communicating to ships and aircrafts relaying telephone calls and providing communications. C Fiber optic cables d Copper wire Answer. The protection used in optical fibers means it blocks external interference very effectively.

Bc fiber optic cabling uses light instead of electrical signals it is immune of most types of eavesdropping. Satellite versus Fiber Optics communication1- Fiber optics communication is quicker but satellite is slow in communication2- Fiber Optics communication higher bandwidth but Satellite Lower. Attitude and Orbit Control System AOCS consists of four major parts.

It uses optical fibers to transmit data via light signals instead of using the slower form of pulses of electricity. The basic differences between a passive and an active communication satellite arise from the fact whether the communication relay involves passive reflection or an active electronics system. There are a number of differences between satellite based and terrestrial wireless communications that affect design.

Uplink transponder and downlink are the three stages of satellite communication. The difference between Satellite Communication and Optical Communication are as follows. To this end efforts are being made to initiate development of experimental satellites having transmission speeds at.

In satellite communication satellites as a relay station are used for communication. What is the difference between baseband coaxial and broadband coaxial cable. Optical communication uses the light rays as a medium of propagation.

Explain types and multiple access communication. Weisz in Encyclopedia of Physical Science and Technology Third Edition 2003 VID Satellite Service. Explain about the optical detectors.

A satellite transmitter operates at 4 GHz with transmitter power 0f 7W and an antenna gain of 40 db. Explain about satellite link models. Fiber offers a connection that has 26000 times more transmission capacity than twisted pair cables however it foes come at a much higher cost.

The receiver has an antenna gain of 30db and path length is 40000 Km. The differences between a Major Earth Station and a VSAT VSAT Very Small Aperture Terminal A VSAT is typically a small earth station 07M to 37M Usually operates a single service or application Major Earth Station Typically A Major Earth station is sized from 37M to 16M weighing 20 T or mo re costing 1M. Samacheer Kalvi 12th Physics Communication Systems Additional Questions.

Digital Subscriber Line DSL Cable Modem Fiber Wireless Satellite Broadband over Powerlines BPL The broadband technology you choose will depend. I dB No losses due to cable bends. Diode Optical Fiber System Link Budget.

Microwave communications are used for short-range communications while satellite communications can be established over long distances. A GEO satellite with one single antenna can. Most satellite usage however is for the fixed services where satellite relay systems are operated by international or national communications companies.

A Mobile b Satellite c Fiber optics d Internet Answer. Because very large areas of the earth are visible from a satellite the satellite can form the star point of a communications net simultaneously linking many users who may be widely separated geographically. Explain about geostationary satellites.

Explain briefly about Geo stationary satellites. Module-III and IV 20 Hours Satellite System Keplers Law Satellite Orbits Spacing and Frequency Allocation Look Angle Orbital Perturbation Satellite Launching Earth Station Satellite Sub-systems Satellite System Link Models Link Equations Multiple Access Direct Broadcast Satellite Services. Transponder and a downlink model for a satellite system.

Broadband includes several high-speed transmission technologies such as. Four 5 km sections of optical cable each with a Joss of 05 dBkm Three cable to cable connectors with a loss of 2dB each. Network topologies connect individual devices.
