Geostationary orbit

accomplished with this technology and what have we yet to discover. From the beginning of the invention of satellites, technology has been evolving and enabled change that has given the world advance uses of communication. To look at changes satellites have brought towards the field of communication we need to look into the history of them. The first communication satellite to be used was released by America called ECHO 1 in 1960. This satellite reflected signals sent from earth via radio waves (The Satellite ECHO 1 1960).It was the first step for worldwide communications. The biggest breakthrough with satellite communication was the launch of geosynchronous and geostationary orbit satellites. These satellites enabled round the clock connection previous low-earth orbit satellites were unable to perform. The first successful geostationary satellite was SYNCOM 3; this satellite broadcast the 1964 Tokyo Olympics to the USA. It was the first transoceanic TV broadcast (Rosen, H. A. 1984). The accomplishment of SYNCOM prompted the improvement of satellite frameworks for both universal and local applications. The competition that followed among local satellite frameworks has brought about various imaginative administrations. With the success of the SYNCOM satellites, came a new era of communication giving the industry new ideas. We can see from 1957 to 1964 the technology in satellites evolved dramatically from the reflection of radio signals to transoceanic TV broadcasting. The…

the first in 1962. Currently, there are more than 1,100 publically and privately owned active communication satellites in orbit with more than 2,600 inactive ones causing a significant amount of space debris. Importantly, communication satellites provide our security and our entertainment. At a high altitude of nearly 36,000km from Earth, the geosynchronous orbit (GEO) is an ideal location for communication satellites that have a requirement to be over the same position of Earth. This “sweet…

earth. The discussion below will support the design for a nuclear powered “spy” photographic satellite in low earth orbit, possessing a10-meter telescopic mirror, and using microwaves to transmit photographic data to earth. Location: There are four orbits…

the space environment becomes more and more important, because no one knows what kind of changes will appear or if it will impact out planet. Introduction Space junk is an assortment of waste and debris that includes derelict satellites, pieces of busted up rockets and other defunct objects floating around Earth’s orbit. Orbital debris can be made intentionally like destroying a weather satellite using a ballistic missile (United Nations 3). On the other…

brightness. A transit is when a planet appears to move across the face of a star, dimming the brightness. A planet has to complete 3 or more transit periods, which is when the planet essentially makes a full orbit around the star three times, before astronomers will assume that an exoplanet is responsible. If those three periods are not made, it can be assumed that it was an asteroid, comet, etc. that was just flying through the sky. Granted, that while that asteroid would have to be fairly…

1. What are Kepler’s 3 Laws. Explain each law in detail and why it is important in astronomy. (3 pts) Kepler’s Three Laws that everything orbits the sun. The first law is that everything orbits the sun, all the planets orbit in the ecliptic of the sun which clear up a lot of the problems with the tycho model in retrograde motion. Ellipses. The second law is equal areas in equal times. Equal Areas. And the third law is the mathematical relationship equating distance from the sun, average…

comparison between the motion characteristics of different planets. The comparison being made is that the ratio of the squares of the periods to the cubes of their average distances from the sun is the same for every one of the planets. As an illustration, consider the orbital period and average distance from sun (orbital radius) for Earth and mars. The T2/R3 ratio is the same for Earth as it is for mars. In fact, if the same T2/R3 ratio is computed for the other planets, it can be found that…

without the aid of a telescope, developed three laws which described the motion of the planets across the sky. Kepler's 1st Law: The Law of Orbits, Kepler's 2nd Law: The Law of Areas, and Kepler’s 3rd Law: The Law of Periods. Kepler's laws were derived for orbits around the sun, but they apply to satellite orbits as well. In retrospect, the reason that the orbit of Mars was particularly difficult was that Copernicus had correctly placed the Sun at the center of the Solar System, but had erred…

Although space debris may seem trivial, it is in fact crucial in terms of today’s concern over technology. One main problem is the Kessler Syndrome, a scenario in which the density of an object in low earth orbit is high enough that collisions between objects could cause a cascade. Donald Kessler himself wrote, “There’s no doubt about it, a cascading collision of satellites in orbit would definitely affect life on Earth, by disrupting global communication, limit globalization and undermine…

In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions…
