Uses of Satellites Satellites have many uses, from observation satellites both civilian and military to communication, navigation, weather reporting, and research. Now a number of … objects have been put into orbit around various planets, moons and even our Sun. Man-made satellites are typically launched into outer space from earth to collect data, photos and other information about Earth and all the many things that exist around it. However, they typically rank high on the list of expensive telescopes. Examples of these are the , , and spacecraft in orbit over the European continent. But, did you know that the moon is a satellite as well? Applications of Artificial Satellites Following are the important applications of artificial satellites. This is different from the natural satellites, or moons, that orbit planets, dwarf planets and even asteroids.
Weather forecasting Artificial satellites are used for weather forecasting. But microwaves are different; they can penetrate the ionosphere and travel all the way to Mars and even further. Launch into Earth orbit would be done by a foreign provider. The main part of this is as big as a large five-bedroom house, but including solar panels, it is as large as a rugby field. Areas of concern include structure, instrumentation, controls, power supplies, and telemetry for future communications, meteorological, and navigation satellites. Equipment on a satellite is hardened to survive in the radiation and vacuum of space.
In addition, numerous communications satellites have been orbited by commercial organizations and individual nations for a variety of telecommunications tasks. As of 2014, there are about 1,000 operational satellites in space, while nearly 2,600 are non-functional and are space debris. She is pursuing a Ph. Although some manipulation must be done in order to transform digital information into a visible image, it is critical to establish that the manipulation did not distort or otherwise misrepresent the area being depicted in the imagery. Elevation is the extent of the satellite's position above the horizon. In the context of activities planned for the 1957—58 , the announced on 29 July 1955 that the U.
Merits and De-merits 17 8. For instance,here are some of the names of indian satellites: 1. Both of those assemblies are man-made, and both are in orbit around the earth. Archived from on 20 March 2008. The Space Shuttle Discovery docked with the International Space Station.
This is where a satellite takes 24 hours to orbit the Earth; the same amount of time it takes the Earth to rotate once on its axis. On 4 October 1957 the launched the world's first artificial satellite,. Such an orbit can place a satellite in constant sunlight and is useful for , , and. One of the most common ones is geosynchronous orbit. Its products include 1 m panchromatic black and white and true color images in addition to 4 m multispectral imagery.
The best commercial satellites operating in 2005 had resolutions of 1 meter 3. Microwaves play a huge role in space exploration and technology. Artificial satellites are used to take pictures of space so we know what is going on up there and so we can see whats on the planets without going up there and another reason is that it can forcast weather because it is going around the world it can see what is going on with the wind and the clouds so it can help warn the people when there is a tornado or a hurricane coming. Jensen, Chris McMaster, and Chris Rizos editors. A satellite is best understood as a projectile, or an object that has only one force acting on it — gravity. These orbits are sun synchronous, meaning that they cross the equator at the same local time each day.
The first Italian satellite launched on 15 December 1964 on a U. The reconnaissance satellites are used to spy on other countries, They provide intelligence information on the military activities of foreign countries, They can detect the missile launches or the nuclear explosions in space. The are the best sources of data for the climate change research, They monitor the ocean temperatures and the prevailing currents, The data acquired by the satellite-borne radars were able to show the sea levels have been rising by three mm a year over the last decade. Other land use for satellite phones are rigs at sea, a back up for hospitals, military, and recreation. This list does not consider those numerous countries, but only lists those capable of launching satellites indigenously, and the date this capability was first demonstrated. Space Science Before the Space Age, astrophysicists were limited to studying the universe via ground-based telescopes, and so could only use information from the parts of the electromagnetic spectrum that penetrated the Earth's atmosphere. There are other moons that are orbiting asteroids, but only two of them are spherical.
There are dozens upon dozens of natural satellites in the solar system, with almost every planet having at least one moon. Its period is one half day, so that the satellite is available for operation over the targeted region for six to nine hours every second revolution. As a result, bigger and more substantial projects can be conducted to get more reliable results. Optical and are most valuable during the launch; radio tracking is used once the satellite has achieved a stable orbit. Other countries began to send their own satellites into space as the benefits rippled through society. Once above the lower atmosphere, the rocket bends to a nearly horizontal flight path, until it reaches the orbital height desired for the satellite. Prosecutors or plaintiff's attorneys must establish that any processing or enhancement techniques used on the imagery were properly documented and followed accepted professional standards, whereas defendant's attorneys may question the authenticity of imagery used against their clients.
The satellite The communications have the ability to rapidly communicate between a number of widely dispersed locations, They help the big manufacturing companies and the department stores to perform inventory management, They provide the instant credit card authorization and automated teller banking services to even small towns, They pay at the pump gas at the freeway gas stations, and video conferencing for the international corporations. Satellites can even have people in them, like the International Space Station and the Space Shuttle. There are a thousand or more artificial satellites in orbit around the Earth. The first satellite, , was put into orbit around Earth and was therefore in. These higher frequencies, along with more powerful transmitters and larger antennas, permit the orbiters to send the data much faster than the landers could manage transmitting directly to Earth, which conserves valuable time on the. Relay 1 and Telstar 1, both launched in 1962, were the first active communications satellites; Telstar 1 relayed the first live television broadcast across the. Examples of polar-orbiting satellites include weather satellites and reconnaissance satellites.
There are 173 known natural satellites in the solar system. The casing usually falls back to Earth once the satellite is deployed. The United States' first satellite was on Jan. This can be very useful for users who are located in remote areas, and cannot access a connection, or require high availability of services. . They enter orbit around the Earth's atmosphere or travel to other planets after launching through rockets, and remain in the atmosphere for a specific period of time before returning to Earth. This keeps the satellite in the same spot over the Earth, allowing for communications and television broadcasts.
