Why are GEO systems telecommunication currently being replaced by fiber optics?
The delay earth-GEO satellite-back to earth is always about 250 ms. This is very high compared to delays in fibre optics. Nothing can change this fact as (currently) the speed of light is the upper limit for the signal propagation speed and the distance of the GEOs is almost the circumference of the earth.
American satellite launched in 1963?
Syncom 2 was launched in 1963, the worlds first geo synchronous satellite. These are special types of satellites that are launched much further out into higher orbit around the earth. The greater the distance from earth, the longer it takes for the satellite to orbit. You eventually get to a special distance where the time taken to orbit is equal to one day, the same as one spin of the earth, so the satellite can effectively hold a position relative to the surface of the earth. This means they can be easily tracked with stationary satellite dishes.
From earth one satellite appears to overtake another the faster satellite is?
The faster satellite appears to overtake another satellite when observed from Earth. This is because the faster satellite covers a greater distance in the same amount of time, causing it to catch up to and pass the slower satellite.
How are satellite pictures of earth and other planets made and transmitted?
Satellite pictures are taken through the satellite and sent to Earth via satellite waves.
What advantages does a weather satellite in geostationary orbit have over a weather satellite in polar orbit?
A satellite in Geosychronous Earth Orbit (GEO) orbits the Earth in the same time period that the Earth spins, so the satellite appears to be stationary over one spot above the Earth's equator. It's always looking down at the same area of the Earth. A satellite in a polar orbit will pass quickly over any one spot on Earth and keep going. It can't watch the same area for a long period. Depending on the altitude of the orbit, it may take days or weeks to pass over the same area again. However, polar orbits are typically much lower, permitting a much higher resolution image. This is very important for photo imagery, but not so much for weather.
What is full form of GSLV?
geo synchronous satellite launch vehicle
6 What name is given to the orbit of an artificial communications satellite?
Geo
Why isro is located at sri hari kota?
Because south india is nearer to equator than the rest parts of india, so it is easy to launch satellites and set in geo-synchronus orbit and reduce the cost by saving fuel.
What does satnav stand for?
Satnav stands for satellite navigation, which is a system that uses satellites to provide autonomous geo-spatial positioning.
What happens when any object is dropped from a geo stationary satellite?
it revolves in the same orbit
What is a non Geo stationary satellite?
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.
Which task would be best performed by a asatellite in GEO?
A satellite that is in GEO, or geostationary orbit, is one that is at a fixed position above the Earth. A task best performed by this type of satellite is one that involves monitoring one area continuously for changes.
What is the significance of the geo orbit radius in relation to satellite communication?
The geo orbit radius is significant in satellite communication because it determines the satellite's position relative to the Earth. Satellites in geostationary orbit, which have a radius of about 22,236 miles, appear stationary from the Earth's surface. This allows for continuous communication with fixed ground stations, making them ideal for services like television broadcasting and weather monitoring.
How far must a geostationary communication satellite orbit?
Geo-stationary communication satellites are 35,768 Km far from earth surface at an equatorial latitiude.
Why do people who live near the north pole have trouble receiving signals from geostationary satellites?
A geo-stationary satellite is 35,560 km above the equator. If you're sitting at thenorth pole looking at that satellite, you're looking 8.6 degrees below your horizon.That's a tough direction to receive satellite signals from.
What is a car's Sat Nav used for?
Sat Nav is short for Satellite navigation system. Sat Nav is a system of satellite that provides geo-spatial position with global coverage. When used on a car, sat nav tells where exactly the car is.
Low Earth orbit satellite period of revolution?
umm if my calculations are correct the period of a low earth orbit (LEO) is approximately 40000000000069 years. as extrapolated from Kepler's equation.
