Introduction A satellite is an object that revolves around a planet in a curved path. When it comes to satellites, there are two major types of classification. The first is a natural satellite, and the second is an artificial satellite. A natural satellite is one of the celestial bodies that orbit a larger body in space. Other than planets and their moons, natural satellites such as comets and asteroids exist. Artificial satellites are satellites that are built by humans and launched into orbit using rockets. Artificial satellites include navigation satellites, weather satellites, communication satellites, and so on. This article will ... Read More

Introduction All the planets in the solar system are found at different distances. The first four planets are closer to each other and closer to the Sun. They form the inner solar system. The planets in the outer solar system are far away from the Sun. Remote censoring is the collection of information about objects on Earth from a distance without direct contact. It has a long history, beginning in the 28th and 19th centuries with photographic instruments mounted on balloons and pigeons’ legs and continuing through the era of remote sensing. During the 20th century, aerial photography and satellite ... Read More

Introduction Wave is the disturbance in the medium to transfer energy without the transfer of mass. Waves are usually in a periodic motion like a simple harmonic oscillator. They have crests and troughs. The amplitude of the wave is the height of the wave. The distance covered between two consecutive crests is called the wavelength of the wave. The number of waves passed per second is called the frequency of the wave. Phase is not the property of waves. But it gives the relation between two signals with the same frequency. Fig:1 Propagation of wave Classifications of the waves ... Read More

Introduction The Pulse Amplitude Modulation is referred to as a very simple model of signal modulation technique. These are the signals that are further transmitted and are inspected at a very particular interval. On top of it, the modulating signal is proportional directly to the amplitude of the signal Therefore it general multiple carrier signals like frequency, bandwidth and amplitude which are also its core features. This particular phenomenon is also an outcome because of adding details to the carrier signal in the course of transmission. What is meant by Pulse Amplitude Modulation (PAM)? Figure 1: Pam ...

Introduction Electronic communication systems dissolve the communication power to both the positive and negative impacts. Analogue or digital signals are fed to the system, processed in the circuits electronically for transmission and then deduced by the receiver. Electronic communication systems are said to be highly reliable and efficient when the errors are minimised in the procedures. Social networking is the most utilised electronic communication system among the rest. People utilise mostly to share their opinion, and views on a respective matter through the assistance of social media platforms. What is an electronic communication system? Electronic communication is referred ... Read More

Satellite Communication

Updated on 13-Oct-2022 11:19:47
Introduction A satellite is a smaller object that is built for collecting information about the happenings in the space. Satellite communication on the other hand, is the process of sharing information between the satellite and the earth's stations. This communication ensures that people on earth are being updated about the small to big happenings in the space. In simple words, satellite communication is an electromagnetic way of making contact with space and collecting information for research purposes. Definition of satellite communication Satellite communication refers to the process of sending and receiving electromagnetic waves for constructing communication between the earth ... Read More

Satellite Communication Active and Passive Satellite

Tutorialspoint
Updated on 13-Oct-2022 11:19:47
Introduction In order to shape telecommunication in the present day, satellites are considered one of the crucial parts of the entire communication system. The presence of artificial satellites helps in receiving a fast and easy transmission of both kinds of signals such as analogue and digital. Focusing on this particular parameter of telecommunication the parent tutorial will discuss satellite communication in a brief manner along with defining the active and passive satellites. What is Satellite Communication? Figure 1: Satellite communication Satellite communication can be defined as the particular communication that is established with the help of different stations present ... Read More

Remote Sensing

Updated on 13-Oct-2022 11:19:47
Introduction Remote Sensing is one of the scientific methods that help to detect the physical properties of an area. This process is done without having any physical contact with the targeted objects. This process is mainly used for gathering information about different solar planets and Earth. Different types of fields like geology, ecology, meteorology, hydrology, geography, and glaciology used the method of Remote Sensing. Many other fields like military, planning, economics, and intelligence also used this method of sensing. Definition of Remote Sensing Remote Sensing technology is mainly used for gathering information on the Earth's surface without making ... Read More

Special Theory of Relativity

Introduction Special theory of relativity is one of the most important theories in the field of physic. Special relativity describes the relationship between energy and mass. The theory further states that a small amount of mass can be transposable with a huge amount of energy. It is defined by the famous equation $E = mc^{2}$. The special relativity is applied in special cases. The theory is mostly used in the discussion of high energy, astronomical; distance, and ultra-fast speed, all without the complexity of gravity. In 1905, Einstein added gravity to his theories when he published his paper on general ... Read More
