There are several thousand. About 30 of them are GPS satellites, and another several dozen are geosynchronous communications satellites that provide TV programming and telephone service. There is the Hubble Space Telescope, the International Space Station, and hundreds of weather satellites.
The first man-made satellite was Sputnik, launched into orbit in 1957 by the Soviet Union. The first American satellite was Explorer, launched the following year. The oldest satellite still in orbit is Vanguard, launched in 1958 by the US. There are now thousands of satellites currently in orbit, including communications satellites, GPS satellites, and the International Space Station. if you would like to see a real-time 3-D plot of satellites now in orbit, check out the JTRACK 3D web site from NASA.
Saturn has only on artificial satellite revolving around it named "Cassini"Cassini--Huygens
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
No, you cannot display arbitrary video on the screen of a GPS navigation unit and many GPS receivers have no screen (e.g. a GPS tracking recorder used on commercial vehicles).GPS is a system maintained by the US Air Force consisting of 3 segments: the space segment composed of 24 active satellites and 6 idle spare satellites, the ground segment manned by US Air Force officers that monitor and control the satellites remotely, and the user segment composed of receivers that decode the signals from the satellites to calculate latitude, longitude, and elevation.
Asteroids are celestial objects made of rock or metal that orbit the sun, while satellites are artificial objects placed in orbit around a planet or moon. Asteroids vary in size from a few meters to hundreds of kilometers, while satellites are typically much smaller in size and are man-made. Asteroids can be found throughout the solar system, while satellites are specifically designed and launched by humans for various purposes such as communication, navigation, or scientific research.
3 Planetary Satellites are; The Moon, Io, Titan. 3 Satellites of the Sun are; Earth, Mars, Jupiter.

artificial and natural satellites lang ang alam ko artificial satellite an object that orbits another object know as its primary.The term is often used to describe an artificial satellite.Artificial satellites should be compared to another satellite in orbit around the earth which are not man made ad therefore natural satellit. ^__^ natural satellite has no us as such. sana makatulog po ito <3
3 GEO Satellites located at 120 degrees are required to cover whole of the earth.
Five artificial satellites that are orbiting the earth are ACRIMSAT, HAMSAT, OSCAR 3, PicoSAT and RADARSAT. There are scores of satellites that orbit the Earth for one reason or another.

Pakistan has sent three satellites into space. All three satellites have been named as Badar 1, Badar 2 and Badar 3 consecutively.
There are 168 known natural satellites (moons) of the 8 major planets. There are also moons around 3 of the 5 dwarf planets (Pluto, Eris, and Haumea). There are more than 200 artificial satellites (or expired satellites) in Earth orbit or scattered throughout the solar system.
Neither Mercury nor Venus have natural satellites. Earth has one natural satellite and several thousand artificial ones. All of the other planets have at least two (Mars) or more.
It has 3 satellites!
