Is a GPS system based on a constellation of four satellites strategically placed around the Earth?
No, for GPS to work there must be 24 operational satellites in orbit, with 12 of those above the horizon as seen from any point on earth.
For a GPS receiver to get a latitude-longitude fix it must receive signals from a minimum of 3 satellites and to also get altitude it must receive signals from a minimum of 4 satellites. Each satellite that it receives above these minimums allows the receiver to get a more precise fix.

What is anything that revolves around a planet called?
Objects such as moons or satellites that revolve around a planet are typically referred to as "natural satellites" or "moons." Artificial satellites placed in orbit around a planet are simply called "satellites."
How many geo stationary satellites are needed to cover the earth at a time?
Please be a little more precise in your meaning when you say "cover" the Earth. For radio or TV communications, three satellites in geosynchronous orbit will be visible from any inhabitable locale on the planet. (The polar regions aren't really "inhabitable", and aren't visible from GEO. ) For navigational purposes, more are required. The GPS system requires line-of-site to FOUR satellites at one time in order to give a good "fix" of your position; the USAF uses 27 satellites to accomplish this, anywhere on the Earth.
Difference between artificial and natural satellites?
Artificial satellites are man-made objects placed into orbit around Earth for various purposes, such as communication, navigation, weather monitoring, and scientific research. Natural satellites, on the other hand, are celestial bodies that orbit planets or dwarf planets, such as Earth's moon, which occur naturally in the universe.
What are the satellites placed 200 - 800 kilometers above earth?
Satellites placed 200 - 800 kilometers above Earth are typically used for Earth observation, communication, and scientific research. These satellites are considered low Earth orbit (LEO) satellites and offer advantages like lower latency for communication and higher resolution for imaging compared to satellites in higher orbits.
What is a astronomical body that revolves around a larger body called?
An astronomical body that revolves around a larger body is called a "satellite." This term can refer to natural satellites, like moons that orbit planets, or artificial satellites, which are human-made objects placed into orbit around a celestial body. The larger body being orbited is often referred to as the "primary" or "host" body.
What is anything that revolves around a planet called?
Objects such as moons or satellites that revolve around a planet are typically referred to as "natural satellites" or "moons." Artificial satellites placed in orbit around a planet are simply called "satellites."

How does a satelite get into space?
Some natural satellites were created there, but artificial satellites are placed there using rockets.
Why is the delphinus the constellation placed in the sky?

What are the two kinds of satellite?
The two main types of satellites are natural satellites, which are celestial bodies that orbit planets, and artificial satellites, which are man-made objects placed into orbit around Earth for various purposes such as communication, weather observation, and navigation.

How does satellites avoid collision?
The vast majority of satellites are in geo-stationary orbits. This means, they travel around the Earth at the same speed that the Earth rotates - making them appear in the same place. One example is the GPS satellite network. Other satellites that actually orbit around the Earth, are at a different altitude - so they would (thoretically) never collide with a stationary one. Those that are orbiting, are placed in such a way, that they also avoid each other.
Why was the constellation Orion placed in the sky?
Orion was placed in the sky in Greek mythology to honor a great hunter named Orion who was killed by a scorpion. The gods took pity on Orion and placed him in the sky as a constellation to immortalize him.
Are moons and satellites the same thing?
In astronomy, the term "moon" specifically refers to a natural satellite that orbits a planet, like Earth's moon. Satellites, on the other hand, can refer to both natural moons and artificial objects placed into orbit around planets. So, while all moons are satellites, not all satellites are moons.
