DMSP, or Defense Meteorological Satellite Program, satellites were initiated by the Department of Defense. These satellites are used to provide important information to the military concerning weather conditions. Most commonly this information is used by the Air Force.
Strategic and tactical weather prediction.
"Natural Satellites"
Circle around larger, more massive objects (the Earth is technically a satellite of the Sun, and the Moon is a natural satellite of the Earth).
Artificial Satellites
Satellites orbit the Earth to provide links between places on the planet (TV, phone, internet) and to study the Earth and space. They provide information to the military, to weather forecasting, to geologists, and more. The orbiting space telescopes examine other planets and stars.
Satellites orbit in a variety of directions, but most circle west-tp-east at various heights above the Earth's atmosphere. Geostationary satellites seem to stay in one place, but they only in very high orbits. Geosynchronous satellites orbit exactly once a day, so they stay over the same location on the ground.
(see related question)
Because of the large distance between satellites, distances from Earth to distant stars and planets can be determined more accurately (greater parallax). Also, on board cameras can better view objects on Earth in 3 dimensions.
There are many purposes for placing satellites in orbit. First and foremost, communications satellites exploit their great distance from the earth to transmit their signals the greatest distance possible. Many modes of communication, chief among them microwave, travel by 'line of sight,' meaning that one must be in a direct, unobstructed sight line in order to receive a signal. The earliest communications satellite received and relayed microwave communications from large ground stations. Today, we have technology to communicate directly through such satellites using satellite phones. Satellite communication permits direct communication beyond the horizon that might not otherwise be possible with conventional VHF (Very High Frequency) communication (ie, radio).
Still other satellites are used for assorted experimental purposes, exploiting the lack of vibration, low temperature and low gravity of space as an ideal location for extremely sensitive instruments, such as the Hubble Space telescope and similar projects, which are able to see much deeper and more clearly into the cosmos without having to look through the earth's atmosphere first.
A special category of satellite is one that is manned, such as the International Space Station (ISS), and they are used for exploration and research into the effects of long-term low gravity, international cooperation and the promotion of peace, among other purposes.
Communication satellites can be used to send telephone messages or TV pictures. A satellite can be used for working out what the weather will be like in a few days. It has a sensor which send a television call to earth telling us what's going to happen. They can also be used for spying and navigation and they can spot forest fires and water pollution.
1st letter is S and ends with E!
it transmits radio/ televideo/etc. waves
It helps us by like if we atrapped some where and u have afone on u u can call 911 or someone who willhelp u
They are used for exploring different planets in our solar system, transmitting radio, telephone, and television signals, and to tell what the weather is going to be like.
many sencitest send artifical satalites some revolving around the earth. it is used dish antena
The primary uses for an artificial satellite, given our current technology, are:
As our technology continues to expand, it's likely that uses for artificial satellites will as well. For example, a military satellite might provide a way to defend specific nations, or even the Earth as a whole (from a meteor strike, for example). Or, as seen on sci-fi TV shows, a space dock could allow the repair and refueling of space vehicles, without the need to return to our planet's surface. There could eventually be space hotels, low- and zero-gravity tourist attractions, zero-gee factories, controlled-gravity hospitals... The list is bounded only by our imagination, and economic considerations.
We really depend on satellites and they help us out in every day life. Satellites help us to know what the world looks like. They also help us to travel, prepare for good and bad weather.
they benefit the society
A satellite is built up of microscopic telescopes with cameras and mirrors. They have strong sight and can spot objects or different planets or stars from millions of miles away. They then collect the data and that data is sent through signals into a giant dish with antennas that send the data through wires and into the computers for astronomers or scientist to examine.
How - they are built from metals, ceramics and carbon materials. Why - for weather information, national security, as telescopes (Astronomers can see better outside of the atmosphere), for telecommunications {no satellite, no texting.} You can do things on a satellite that cannot be done inside Earth's atmosphere.
Satellites orbit a central mass of some sort as a result of gravity. Complex orbits can be the result of multiple gravitational sources.
The planets in a solar system can be considered satellites of the central star (or stars).
The moons orbit the planets they are near.
Normally staellites are by convention smaller then the objects they orbit.
A note: Not all orbits of satellites are stable and most orbits decay over time. The moon around Earth will someday either go zipping off or come crashing down at some point.
Many artificial satellites periodically use on-board systems to maintain their orbit and occasionally alter their orbit to avoid debris and on rare occassions and a rare number of sattelites, shelter themselves on the far side of a planet to protect against "bad solar weather."
There are a number of different reasons.
The first few satellites were sent up just to see if it could be done. The first few Sputnik satellites did nothing other than send radio beeps, and the first few Vanguard birds did little more.
Then there were weather satellites, and then communications birds, and then some navigation satellites. Now there are several THOUSAND active satellites in orbit, with dozens of varied purposes.
different satellites have different purposes. Communication, scientific study and research, etc

For many reasons some being meteorology, communications, geographic mapping, spying, entertainment, and scientific studies of Earth and space.
Super has been to natural satellites but hasn't been to artificial satellites
All the satellites, communications, exploratory, military etc. are artificial satellites of Earth.
One type of artificial satellite is called a navigation satellite. Two other kinds of artificial satellites are called weather satellites and communications satellites.
Give two purposes of artificial satellites.
Artificial satellites are manufactured in laboratories. Natural satellites coalesced from the primordial cloud.

First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon
Mercury has no natural nor artificial satellites.
There are two kinds of satellites: the artificial and natural satellite.
