Introduction to Satellite Communication Handwritten Notes
As a rule term, a satellite is a more modest item that rotates around a bigger article in space. For instance, the moon is a characteristic satellite of the earth. We realize that Communication alludes to the trade (sharing) of data between at least two elements, through any medium or channel. All in all, it is only sending, getting, and handling of data. On the off chance that the correspondence happens between any two earth stations through a satellite, at that point it is called satellite correspondence. In this correspondence, electromagnetic waves are utilized as transporter signals. These signs convey the data, for example, voice, sound, video, or some other information among ground and space and the other way around. The Soviet Union had dispatched the world’s first counterfeit satellite named, Sputnik 1 out in 1957.
Almost following 18 years, India likewise dispatched the fake satellite named, Aryabhata in 1975. The accompanying two sorts of spread are utilized before for correspondence up to some separation. Ground wave proliferation − Ground wave spread is reasonable for frequencies up to 30MHz. This strategy for correspondence utilizes the lower atmosphere states of the earth. Skywave proliferation − The appropriate transmission capacity for this sort of correspondence is extensively between 30–40 MHz and it utilizes the ionosphere properties of the earth.
The most extreme jump or the station separation is restricted to 1500KM just in both ground wave spread and skywave proliferation. Satellite correspondence conquers this constraint. In this strategy, satellites give correspondence to significant distances, which is well past the view. Since the satellites situate at certain stature above the earth, the correspondence happens between any two earth stations effectively by means of satellite. Thus, it conquers the restriction of correspondence between two earth stations because of the earth’s ebb and flow.

What is an Elliptical Orbit?
When an object moves around another object in an oval shaped path, it is known to be revolving in an elliptical orbit. All planets move in elliptical orbits around the sun. The Moon also moves around earth in an elliptical orbit. It moves fastest when it is closest to the Earth due to the Earth’s strong gravitational pull and moves slowest when it is furthest from the Earth. Elliptical orbits are best suited for communications satellites, as it allows the satellite to be visible to a ground station for a long portion of its orbit, and is out of contact for a shorter period of time. The size of an ellipse is measured by the major and minor axis. The major axis measures the longest distance across the ellipse while the minor axis measures the shortest. The point at which the satellite is closest to the earth in an elliptical orbit is called the perigee. The point at which the satellite is farthest from the earth in an elliptical orbit is called the apogee.
What is the Medium Earth Orbit (MEO)?
The region of space in between the low Earth orbit and the geostationary orbit is called the Medium Earth Orbit (MEO). This orbit is at a distance of 2000 to 35786 kms from the earth’s surface. This orbit is ideal for navigation and communication satellites. Some examples of satellites that operate from this orbit include GPS (Altitude of 20,200 kilometers), GLONASS (Altitude of 19,100 kilometers) and Galileo (Altitude of 23,222 kilometers). Communication Satellites covering the North and South Pole also revolve in MEO. The MEO satellites have an orbital period ranging from 2 to 24 hours. Telstar, the first experimental satellite launched in 1962, also orbits in MEO.

What is Multi-Paction?
RF Devices in Satellite communication systems, including filters and multiplexers are subject to high RF power levels. These high power levels can lead to a unique nonlinear breakdown voltage phenomenon in a vacuum or near-vacuum environment called Multiplication. This effect can render a device useless and, thus degrades the reliability of the satellite. All high power devices that are used in space have to be analyzed with regards to their breakdown behavior.
Multi-paction occurs in a vacuum when free electrons present in a satellite device are accelerated toward the walls of the device (usually a waveguide) with enough energy, that their impact against the wall could result in secondary electron emissions. As this process is repeated millions of times per second, the number of electrons multiplies rapidly, leading to a multi-paction discharge. This discharge is usually releases a small amount of power, however causes increased outgassing in the component or system, which can lead to a gas discharge. A gas or corona discharge in a space system can release a large amount of power, thus causing component performance degradation or even system failure.
