Relates the orbital planes position to the earth. Counteracting jets must be placed when the inclination is at zero to halt the change in inclination. Log In Sign Up. What is an TDMA? This is ec20445 a Hohmann transfer is fuel efficient. Skip to main content. Explain in detail about speech interpolation and prediction. What does the term dilution of precision refer to?

Three conditions are required for an orbit to be geostationary: Reduction ec satellite communication notes primary power reduces satellite life During eclipse it is necessary to shut down some transponders, and results in reduction of coommunication performance.

An antenna has a noise temperature of 35 K and it is matched into a receiver which has a noise temperature of K.

satel,ite Explain uplink satellite circuit. Write short notes on station keeping. Satellite Communication Type of Study Materials: What is an EIRP? A satellite downlink at 12 GHz operates with a transmit power of 6 W and an antenna gain of The height of the terrain above the communnication ellipsoid at the sub-satellite point is denoted by H ec satellite communication notes The height of the satellite above this, by h ss. Define apogee and perigee.


EC2045 Satellite Communication Lecture Notes

Gauhati University Question Paper Semester: The line joining the perigee and apogee through the center of the earth. Mention the apogee and perigee height.

Write short notes on station keeping. Telstar was the first active, direct relay communications satellite. The acceleration satellie an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Small Fading margin 3dB Angle of inclination R.

What is an multiple access technique? Types of launch vehicles: Causes of eclipse During full eclipse, satellite receives no power from solar array and relays only on batteries. Madam this presentation is very useful and really good. Describe briefly about the rains effects. Some examples are weather ec satellite communication satdllite and communications satellites.

What is an inter modulation noise? Classification of orbits R. Explain the classifications of system noise temperature. And also derive the expression for maximal sequence.


Orbit Satellites move in a path around the Earth called an orbit. The limits will be set by the geographic coordinates of the earth station and the antenna elevation.


Satellite Communications full notes, pdf, e-book thank you sir for uploading this notes very help full. If the satellite were at the perigee, the mean anomaly would be 0. Describe briefly the video compression process used in MPEG What is an OMT? Describe briefly the most common type of high-power amplifying device used aboard a communication satellite. What is noise power spectral density? Describe the main features of Radarsat.

What are the methods of multiple access techniques? After a couple of orbits, during which the orbital parameters are measured, the final stage is reignited and the spacecraft is launched into a geostationary transfer orbit GTO. Take satellige that describe what you are saving in the receiver. Explain ntoes detail about topocentric-horizon coordinate system which is based on the www.

A satellite downlink at 12 GHz operates with a transmit power of 6 W and an antenna gain of Types of notrs R.
