Satellite Orbit Ppt

In the simplest sense orbits are a type of racetrack in space that a satellite drives around.

Satellite orbit ppt. Powerpoint ppt presentation free to view. If there is any change in satellite orbit then it sends a signal regarding the correction to orbit control subsystem. Polar orbit and sun synchronous orbit sso satellites in polar orbits usually travel past earth from north to south rather than from west to east passing roughly over earth s poles. Satellites a satellite is a body which is constantly revolving in an orbit around a planet 3 artificial satellites o it is a man made object placed at a height above the earth and given sufficient velocity so as to revolve round the earth in a closed orbit.

Low earth orbit leos medium earth orbit meos global positioning system gps geostationary geos applications 3. Satellites in a polar orbit do not have to pass the north and south pole precisely. A grinding wheel initially at rest rotates with a constant. The ttcm subsystem present at earth station monitors the position of satellite.

We can calculate the look angles of geostationary orbit by using longitude latitude of earth station and position of satellite orbit. An orbit is a closed path around which a planet or satellite travels. These two angles are helpful in order to point at the satellite directly from the earth station antenna. So the maximum gain of the earth station antenna can be directed at satellite.

This orbit is most useful orbit for communication purposes. Inclined orbit the path along which satellite moves in the space around earth are called orbits. By the time the satellite crosses back into daylight it is over the region adjacent to the area seen in its last orbit. Once in daylight and once in darkness.

Even a deviation within 20 to 30 degrees is still classed as a polar orbit. As the satellites orbit the earth turns underneath. In a 24 hour period polar orbiting satellites will view most of the earth twice. There are many different types of orbits which are described by various orbital elements.

Satellites overview history launching of satellites how satellites work orbit distance types. Geosynchronous satellites orbit the earth at a distance of 42 000 km from the earth s center. O first artificial satellite o sputnik i o by russian scientists in 1957. Nearest point on the orbit of a satellite from earth.

E g nasa aura satellite 705 km altitude has a 16 day 233 orbit repeat cycle.
