The point at which a line between the satellite and the centre of the Earth intersects the Earth's surface is called the subsatellite point.
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
Both of those words refer to points in the orbit of an earth satellite ... the moon or any artificial satellite. Apogee . . . the point in the orbit where the satellite is farthest from the earth. Perigee . . . the point in the orbit where the satellite is closest to the earth.
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
Commercial satellites are in geosynchronous orbit around the equator. They are each at a particular longitude. The direction you need to point your dish then depends on where you are. In northern Canada, dishes point at a very shallow angle to the south. In California, they are pointing around 45 degrees up and some amount east or west. Find out the longitude of the satellite you want and then look up on the satellite company's website (or do an Internet search) for the angles to aim (one angle is skyward, the other north/south/east/west).

The current sub-solar point is the point on Earth's surface where the Sun is directly overhead. Its location changes throughout the day due to Earth's rotation and the tilt of its axis. You can track the sub-solar point in real-time using online tools or apps.
what are subpoints
Apogee is the point at which a satellite in an elliptical orbit is At its apogee, the satellite travels slower than at any other point in its orbit.
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
a sub point is detail to back up your main point for examplelets say i wanted to write a paper about myselfmy main point : first i would like to start off with my childhood....sub point: in my early childhood i would always cry for my grandma.....
The "sub-solar point" is the point on Earth where the Sun is straight up, at a 90 degree angle to the ground. This point moves around the Earth each day as the Earth rotates, and appears to move north and south over the course of the year. The sub-solar point is exactly on the equator at the moment of the two equinoxes. In March, the sub-solar point is moving north as it crosses the equator; in September, the sub-solar point is moving south across the equator. In June, the sub-solar point creeps up to the Tropic of Cancer and then heads south again. In December, the sub-solar point gets all the way south to the Tropic of Capricorn at the winter solstice.
Satellite imaging. If you superimpose a satellite image of the Earth at a specific point with a satellite image of air pressure, and then expand those two images forward in time, you can get a decent estimate of what the whether is and is going to be at that point.
It is the sub-solar point. It is the point where the Sun is directly overhead. The sub-solar point has a latitude equal to the Sun's declination at any moment, so all points on Earth between latitudes of ±23½ degrees can be the sub-solar point. If you want to know the direction to the sub-solar point at any instant from where you are, just point at the Sun and then move your arm vertically downwards so that it points horizontally. If you want to know the distance to the sub-solar point, measure the Sun's angle relative to overhead where you are. The distance (in nautical miles) is 60 times that angle in degrees.
Satellite surveying is a form of land survey that uses location information provided by the GPS satellite system to track the location of each reference point.
No. What would be the point?
Sub Zero?
