What else can I help you with?
Why do communication and weather satellites always appear at the same place in the sky?
That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.
Why does a satellite travel over different parts of the earth?
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
Where are the satellites?
Satellites are dispersed in various orbits around the Earth, including low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO). They are positioned strategically to provide global coverage for communication, weather monitoring, navigation, and various other services.
Are Geosynchronous or geostationary satellites capable of performing reconnaissance from space?
Yes, both geosynchronous and geostationary satellites can perform reconnaissance from space, but their effectiveness varies. Geostationary satellites remain fixed over a specific point on the Earth's equator, providing continuous coverage of the same area, which is useful for monitoring weather and large-scale environmental changes. Geosynchronous satellites, while following a similar orbital path, can have inclined orbits, allowing them to cover different regions over time. However, for detailed reconnaissance, lower-altitude satellites in polar orbits are often preferred due to their higher resolution imaging capabilities.
What devices need satellites in geostationary orbits?
Devices such as telecommunications satellites, weather satellites, and broadcasting satellites rely on geostationary orbits to provide continuous coverage over a specific region on Earth. This allows for consistent and reliable communication, weather monitoring, and broadcasting services.
What are the two main types of satellite orbits?
geostationary andGeosynchronous satellites

What type of satellite orbits the earth at 22300 miles above the earth?
A satellite in a geostationary orbit orbits the Earth at around 22,300 miles above the equator. Geostationary satellites appear to be stationary in the sky relative to a fixed point on the Earth's surface, making them ideal for communication and weather monitoring.
Why are some satellites in geostationary orbits while others are in North-south orbits?
Satellites in geostationary orbits are positioned approximately 35,786 kilometers above the Earth's equator, allowing them to match the Earth's rotation and remain fixed over a specific point, making them ideal for communication and weather monitoring. In contrast, satellites in polar or North-south orbits travel over the Earth's poles, allowing them to cover the entire surface of the Earth over time, which is beneficial for Earth observation, reconnaissance, and environmental monitoring. The choice of orbit depends on the satellite's mission and the specific requirements for data collection or communication.

What is a geostationary satellite?
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
What is isochronous satellites?
An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.

What satellite orbits around the earth and takes the same time it takes for the earth to rotate on its axis?
Only artificial, geostationary satellites.
What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
How far above the earth is geostationary orbit?
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
