where do most satellites orbit?
238995
Most scientific satellites and many weather satellites are in a nearly circular, low Earth orbit. The satellite's inclination depends on what the satellite was launched to monitor.

The satellite must be designed specifically to fulfill its role. There are nine different types of satellites i.e. Communications Satellite, Remote Sensing Satellite, Navigation Satellite, LEO, MEO, HEO, GPS, GEOs, Drone Satellite, Ground Satellite, Polar Satellite.

Low Earth orbit (LEO): geocentric orbits with altitudes below 2,000 km (100–1,240 miles). Medium Earth orbit (MEO): geocentric orbits ranging in altitude from 2,000 km (1,240 miles) to just below geosynchronous orbit at 35,786 kilometers (22,236 mi). Also known as an intermediate circular orbit.

A geosynchronous orbit is an orbit around the Earth, where the object orbits once per day. ... A sun-synchronous orbit is an orbit around the Earth, where the movement of the satellite always looks the same when viewed from the Sun.

The Global Positioning System (GPS) is a constellation of about 24 artificial satellites. The GPS satellites are uniformly distributed in a total of six orbits such that there are four satellites per orbit.

Satellites can be either natural or artificial (man-made). Our moon is an example of a natural satellite as are all the moons of the other planets. The earth can also be considered a satellite of the sun. Artificial satellites are put into orbit by man.

Although the exosphere is technically part of Earth's atmosphere, in many ways it is part of outer space. Many satellites, including the International Space Station (ISS), orbit within the exosphere or below.

They're entirely different. A geostationary satellite sits over one spot on the equator. ... A sun-synchronous satellite is in a low earth orbit designed so that the orbit plane precesses eastward at the same rate the earth orbits the sun (360/365.24 = 0.98565 deg/day).

Satellites all have a purpose. Those which orbit the sun do so for a reason, and that defines the mission. ... Solar orbiting satellites study the sun, the other planets, and even comets. Some Earth orbiting satellites do the same thing, like Hubble.

Since then, about 8,900 satellites from more than 40 countries have been launched. According to a 2018 estimate, some 5,000 remain in orbit. Of those about 1,900 were operational, while the rest have lived out their useful lives and become space debris.

Yes, all satellites go in the same direction, they just do so at different speeds. ... A satellite in a geostationary orbit is going around the earth, matching it's rotation speed. If the satellite moves faster, it appears to move from west to east, but, if it moves slower, it appears to move east to west.

Low earth orbit is just above the atmosphere-165 to about 300 miles. ... Geosynchronous orbits are at the other extreme at around 26,000 miles altitude, on 1/10th the way to the moon. Well above the atmosphere, objects in this orbit circle the globe only once every 24 hours, and so appear stationary above the surface.

Although the atmosphere is very, very thin in the thermosphere and exosphere, there is still enough air to cause a slight amount of drag force on satellites that orbit within these layers.
152559
A satellite orbits Earth when its speed is balanced by the pull of Earth's gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. ... Polar-orbiting satellites travel in a north-south direction from pole to pole.

Constellation Arrangement GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km (12,550 miles).

Yes, all satellites go in the same direction, they just do so at different speeds. What everyone else seems to forget, is that the earth is rotating on its axis. A satellite in a geostationary orbit is going around the earth, matching it's rotation speed.

GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20,200 km (12,550 miles). Each satellite circles the Earth twice a day. Expandable 24-Slot satellite constellation, as defined in the SPS Performance Standard.
