There is only one orbital altitude where the satellites do not appear to move; that is the 23,500 mile "geo-synchronous" orbit where communications satellites typically reside. Lower orbits would cause the satellites to orbit more quickly, requiring that the terrestrial antenna be equipped to follow it as it passed over, and to be able to switch to a new satellite once the first one was below the horizon. Since satellite TV antennas are large and not easily movable, a geo-synch orbit makes more sense.

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 are the advantages of utilizing selenosynchronous orbits for satellite communication and observation?
Synchronous orbits, such as geostationary orbits, offer several advantages for satellite communication and observation. These orbits allow satellites to remain in a fixed position relative to the Earth, providing continuous coverage of a specific area. This stability enables uninterrupted communication and observation, making it ideal for applications such as weather monitoring, telecommunications, and surveillance. Additionally, satellites in synchronous orbits experience less orbital drift, reducing the need for frequent adjustments and extending their operational lifespan.
What are the 2 orbits of satellites?
Artificial and natural satellites. Artificial satellites are man-made satellites sent into space for a variety of different purposes e.g. taking pictures of the earth for scientific investigation Natural satellites are moons, which orbit planets and are not man-made.
Can satellites at different heights have equal velocities?
Yes, satellites at different heights can have equal velocities if they are in circular orbits with the same period. In this case, the satellite at a higher altitude will have a slower velocity than the satellite at a lower altitude, but their velocities will be equal at any given point in their orbits.
How does friction with the atmosphere affect the speed of an artificial satellite?
Satellites in a low orbit, however, are slowed by friction with Earth's atmosphere.
What kind of orbits is less than 1500 kilometers above the earth?
Orbits less than 1,500 kilometers above the Earth are typically classified as Low Earth Orbits (LEO). Satellites in LEO can range from about 160 kilometers to 2,000 kilometers in altitude and are commonly used for applications such as Earth observation, telecommunications, and scientific research. Due to their proximity, these orbits allow for lower latency communication and higher-resolution imaging but require frequent satellite passes to maintain coverage.
When did sputnik land?
It didn'tFirst off, sputnik was a "family name" for a series of satellites, but none that was built for re-entry. They burnt up in the atmosphere as their orbits got lower.

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 is the procedure used at the end of the lifetime of a satellite?
Some satellites, those in high orbits, are simply left to uselessly wander. Others, in lower orbits, may be "deorbited" (deliberately crashed) by various means to prevent them from later falling into inhabited areas. See related links for more details.
What atmospheric layer are satellites in?
Satellites are primarily found in the thermosphere, which is the layer of the Earth's atmosphere located approximately 80 to 600 kilometers (50 to 370 miles) above the surface. Some satellites, especially those in low Earth orbit (LEO), operate within the lower part of the thermosphere, while others, like geostationary satellites, are positioned in the exosphere, which extends above the thermosphere. These layers provide the necessary altitude for satellites to maintain their orbits and avoid significant atmospheric drag.
What is satellite Leo?
Satellite Leo refers to low Earth orbit (LEO) satellites that orbit the Earth at an altitude of around 2,000 kilometers. These satellites are used for various purposes such as communication, Earth observation, and scientific research. LEO satellites have shorter orbital periods and are closer to Earth compared to other types of satellites, which can result in faster data transmission and lower latency.
