Satwllite short notes on station keeping. Earth Eclipse of Satellite R. Mention the 3 regions to allocate the frequency ec satellite communication notes satellite services. It is also known as a direct orbit.
EC2045 Satellite Communication Lecture Notes
Satellite Communications full notes, pdf, e-book thank you sir for uploading this notes very help full. 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.
Presentation Description explanation for satellite commuication basics, as per anna university syllabus for first unit satellite orbits. Eec forces mainly consist of Non — spherical nature of earth The attraction of other bodies like sun ec satellite communication notes moon Solar radiation pressure Atmospheric drag R.
Small Fading margin 3dB Angle of inclination R.

Satellite Notea full notes, pdf, e-book Thank you for the upload. Expendable launch vehicle ELV 2. Vernal equinox occurs when the sun crosses the equator going from south to north. Or A satellite is a man-made object launched ec satellite communication notes space to orbit the Earth, moon, sun or other celestial body.
Orbit Satellites move in a path around the Earth called an orbit.
Imaginary line drawn from this equatorial crossing through the center of the ec satellite communication notes points to the first point of Aries. The occurrence and duration of the sun transit outage depends on The latitude of the earth station Receiver location Location of ec particular satellite Size, or more specifically the beam width of the antenna The apparent radius of the Sun as seen from the satelpite about 0.
In the next phase the satellite is injected into an elliptical transfer orbit which ec satellite communication notes an apogee at the height of GEO and its apsides line joining perigee-apogee in the equatorial plane. Frequency allocations for satellite services: Angle between the plane containing c and b B: Some examples are weather satellites and communications satellites. For the antenna beam width to be very narrow, ontes mechanism is required to compensate For the movement of the satellite about the nominal geostationary position For home reception, the antenna beam width is quite broad, and no tracking is necessary.
The orbit must be circular. Two planets are shown on orbits that are the same shape, but the larger orbit is 1.

Explain in detail about topocentric-horizon coordinate system which is based on the. Disadvantages of satellite communications 1.

The disadvantage of this type of orbit is that since these satellites are very far away, they have ec satellite communication notes resolution. The limits will be set by the geographic coordinates of the earth station and the antenna elevation.
And also derive the expression for maximal sequence. Upload from Desktop Single File Upload. Space shuttle also called the space transportation system STS are reusable The solid rocket boosters are recovered and refurbished for nnotes mission and the shuttle vehicle itself is flown back to earth for reuse There are single stage to orbit SSTO launch and two stage to orbit TSTO launch.
Reduction ec satellite communication notes primary power reduces satellite life During eclipse it notess necessary to shut down some transponders, and results in reduction of satellite performance. Post a Comment Enter your comments here. Last edited by jaivinder; 6th January at Explain in detail about ec satellite communication notes look angles and the polar mount antenna.
In this safellite the elliptic orbit or transfer orbit is tangent to both the original orbit A and the final orbit C. Station keeping Even with a very good launch the satellite can drift some what from its orbit.
