Satellite In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon.he first artificial satellite was Sputnik 1, launched by the Soviet Union on October 4, 1957, and initiating the Soviet Sputnik program, with Sergei Korolev as chief designer (there is a crater on the lunar far side which bears his name).

Ground track A satellite with an orbital inclination between zero and ninety degrees is said to be in what is called a direct or prograde orbit, meaning that it orbits in the same direction as the Earth's rotation. A satellite with an orbital inclination between 90 and 180 degrees is said to be in a retrograde orbit. satellite with an orbital inclination between zero and ninety degrees is said to be in what is called a direct or prograde orbit, meaning that it orbits in the same direction as the Earth's rotation.

TEACHERâS GUIDE For AEROSPACE: THE JOURNEY OF FLIGHT A satellite’s orbit depends on its speed and distance from Earth. Below, the main orbit types are listed and defined. 1. LEO (Low Earth Orbit) - When a satellite circles close to Earth, it’s in Low Earth Orbit. Satellites in LEO are just 200-300 miles high. Because they orbit so close to the Earth, they must travel very fast (17,000 mph) so the gravity can’t pull them back into the Earth’s atmosphere. a. Polar orbit-A satellite in polar orbit travels a north-south direction.

How Satellites Work A satellite is any object that moves in a curved path around a planet. The moon is Earth's original, natural satellite, and there are many man-made (artificial) satellites, usually closer to Earth. The path a satellite follows is an orbit, which sometimes takes the shape of a circle.To understand why satellites move this way, we must revisit our friend Newton.Newton proposed that a force -- gravity -- exists between any two objects in the universe.he path a satellite follows is an orbit, which sometimes takes the shape of a circle.

GPS navigation device The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. The first GPS satellite was launched in 1978. 2  A full constellation of 24 satellites was achieved in 1994. 3  Each satellite is built to last about 10 years. 4  Replacements are constantly being built and launched into orbit.

- In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point … is its aphelion and apogee, respectively. 13 people found this useful. Answered.

GPS satellite blocks A GPS satellite is a satellite used by the NAVSTAR Global Positioning System (GPS). The first satellite in the system, Navstar 1, was launched February 22, 1978. The GPS satellite constellation is operated by the 50th Space Wing of the United States Air Force. The GPS satellites circle the Earth at an altitude of about 20,000 km (12,427 miles) and complete two full orbits every day.

satellite A satellite is something small or less powerful that orbits around something bigger. It often describes a body in space, such as an artificial satellite that orbits the Earth and beams down signals that power devices like cell phones. The word satellite was first used to describe a follower of someone in a superior position. The word's meaning later broadened to describe anything small that's dependent on something larger. The small satellite circles around the more powerful force, like a moon orbiting a planet. Satellite can describe a small country — a satellite country — controlled by a larger one, or a large organization that has a small office — a satellite office — in another location.

- Satellite imagery consists of images of Earth or other planets collected by satellites. Imaging satellites are operated by governments and businesses around the world. Satellite imaging companies sell images under licence. Images are licensed to governments and businesses such as Google Maps.

- View the Animation. The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. GPS uses these man-made stars as reference points to calculate positions accurate to a matter of meters. In fact, with advanced forms of GPS you can make measurements to better than a centimeter! In a sense it's like giving every square meter on the planet a unique address.

Satellite state Satellite state. The term satellite state designates a country that is formally independent in the world, but under heavy political, economic and military influence or control from another country. The term was coined by analogy to planetary objects orbiting a larger object, such as smaller moons revolving around larger planets, and is used mainly to refer to Central and Eastern European countries of the Warsaw Pact during the Cold War or to Mongolia or Tannu Tuva between 1924 and 1990, for example.

- Satellites show cloud formations, large weather events such as hurricanes, and other global weather systems. With satellites, forecasters can see weather across the whole globe: the oceans, continents, and poles. Recent satellite data is very detailed, even to the point of showing states and counties.

What is Satellite Communication? Then the satellite amplifies the signal and sent it back to the receiver’s antenna present on the earth’s surface. So, all the signal transferring is happening in space. Thus this type of communication is known as space communication.Two satellites which are commonly used in satellite communication are Active and passive satellites.Passive satellites: It is just a plastic balloon having a metal coated over it. This sphere reflects the coming microwave signals coming from one part of the earth to other part.This is also known as passive sphere.hen the satellite amplifies the signal and sent it back to the receiver’s antenna present on the earth’s surface. So, all the signal transferring is happening in space. Thus this type of communication is known as space communication.

- (NASA illustration by Robert Simmon). The height of the orbit, or distance between the satellite and Earth’s surface, determines how quickly the satellite moves around the Earth. An Earth-orbiting satellite’s motion is mostly controlled by Earth’s gravity.

Definitions &Translations The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Artificial satellites originate from more than 40 countries and have used the satellite launching capabilities of ten nations.

Moon For other uses, see Moon (disambiguation). The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits (its primary).
