Geosynchronous satellites are positioned above the equator to maintain a fixed position relative to the Earth's surface, orbiting at the same rotational speed as the Earth. This allows them to remain over a specific geographic area, which is crucial for applications like communication and weather monitoring. The equatorial orbit minimizes the effects of the Earth's axial tilt and gravitational variations, ensuring stable and consistent coverage. Additionally, positioning satellites at the equator maximizes their coverage area due to the Earth's curvature.

Geosynchronous satellites above the equator do what?
Geosynchronous satellites ('stationary' ones that is) are usually 36 000 km above the Equator, and thus appear to be fixed relative to a given location on earth. They are comm satellites, but because of the distance, the return trip for a signal to them is about 1/4 second. This delay causes trouble with phone comms. You must have been annoyed by those attempts at 'live' TV interviews via such a system. However, for latitudes above say 55o, the sight path to the satellite becomes closer to to horizontal at that site, and may be blocked by buildings, mountains, etc. To service these latitudes, geostationary satellites are positioned to have their rotation plane inclined to the equator. This improves their performance for comms, but at the expense of them no longer appearing to be stationary in the sky.
How far up in the sky are satellites?
There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.
Does Mexico is above or below the equator?
Mexico is located mostly above the equator in the Northern Hemisphere.
Why are there more man made satellites in the southern hemisphere?
There are not. In fact, there are no satellites which remain in either the northern or southern hemispheres. Every satellite spends equal time passing over each of them. The only minor exception would be communications satellites in equatorial geosynchronous orbits, where the satellite is essentially "parked" over one spot above the equator. Elmo: See the Discussion Page for my answer. Thanks.
Is Ukraine above or below the equator?
It is above the equator.
Is the geosynchronous satellites above the equator is follow an elliptical orbit?
All satellites follow an elliptical orbit - they are darn close to circular, but even a circle is an ellipse.
What is meant by a geostationary orbit?
A geosynchronous orbits refers to the orbit of a satellite that matches the rotation of the earth, allowing it to remain above the same line of longitude. The satellite may still move north and south but not east or west. A geostationary orbit is a specific type of geosynchronous orbit directly above the equator. This allows the satellite to remain completely stationary over a fixed point on the earth's surface.
Are satellites in the thermosphere?
Some are (geosynchronous are not).

Why are satellite dishes in the Northern Hemisphere pointed south and in the Southern Hemisphere there pointed north?
Satellite dishes in the Northern Hemisphere are pointed south to align with geostationary satellites above the equator, while in the Southern Hemisphere, they are pointed north for the same reason. This alignment ensures optimal reception and transmission of satellite signals.
Why do you need satellites to be geosynchronous?
Satellites need to be geosynchronous to maintain a fixed position relative to the Earth's surface, allowing them to provide consistent communication, weather monitoring, and surveillance over specific areas. By orbiting at approximately 35,786 kilometers (22,236 miles) above the equator, these satellites match the Earth's rotation, ensuring that they can continuously cover the same geographic region. This stability is crucial for applications like television broadcasting and global positioning systems, where constant signal availability is essential.
Does dbs also known as direct broadcast satellite such as directv and dishtv orbit in a geosynchronous orbit?
Yes, the satellites orbit in a geosynchronous orbit, as with most all communications satellites. (Some exceptions are satellites such as the global positioning satellites.)
How high are the sky broadcast satellites?
22,340 miles above the equator.
A satellite in geosynchronous orbit is always directly above the?
In geosynchronous orbit, it's always somewhere over the same meridian of longitude.In geostationary orbit, it's always over the same point on the equator.
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 kind of an orbit is use by direct tv satellites?
Geosynchronous Orbit
Can people find satellites in geosynchronous orbits on earth s surface?
- No ...
