Let t=0 denote the start of transmission.At t=1 msec,the first frame has been fully
transmitted.At t=271 msec,the first frame has fully arrived.At t=272 msec,the frame
acknowledging the first one has been fully sent.At t=542 msec,the acknowledgement-bearing
frame has fully arrived.Thus, the cycle is 542 msec.A total of k frames are sent in 542 msec,for an
efficiency of k/542.Hence
(a)k=1,efficiency=1/542=0.18%
(b)k=7,efficiency=7/542=1.29%
(c)k=4,efficiency=4/542=0.74%

Which can cause auroras and disrupt satellite transmission?
Which can cause auroras and disrupt satellite transmission?
For satellite communication the frequency should be less than critical frequency?
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
Why do satellite TV frequencies change?
Satellite television frequencies change for various factors the major one being that the particular frequency has become unusable and therefore needs to be changed.
Basic Difference between Active and passive Satellite System?
An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.
Which satellite used for telecommunication?
Geostationary satellite
First Indian satellite in geostationary satellite was?
Aryabhatta
Why doesnt a geostationary satellite trace a path over the surface of the earth?
A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.
Which is the height of a geostationary satellite from the surface is approximately?
The height of a geostationary satellite from the surface is approximately 35,786 kilometers (22,236 miles).
How far above the earth is geostationary orbit?
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
Does a satellite in a geostationary orbit move across the sky from east to west?
No. A geostationary satellite appears to be stationary in the sky, which means not moving. This is a big part of the reason why it is referred to as a geo'stationary' satellite.
Why perfect geostationary satellite can not be made?
It should be possible to have the perfectly geostationary satellites. But it is not possible. Perfectly geostationary satellite can not be made. Such satellite is pulled away by other objects like moon, sun and other planets from different directions. This force changes the velocity of the satellites.
Which is the first geostationary satellite of India?
Aryabhata in 1975
What type of satellite do communication companies prefer?
geostationary
What is the main characteristic of a geostationary satellite's footprint?
its location
How can you tell if a satellite is in a geostationary orbit?
me nuh care
What type of satellite is the g.o.e.s.?
It is a geostationary operational environmental satellite, though I'm not sure what is does.
