Low Earth Orbit Satellite Communication

There is a large variety of other sources that define leo in terms of.

Low earth orbit satellite communication. Most of the manmade objects in outer space are in leo. Traditional communication satellites are stationed far higher at roughly. Project kuiper is a new initiative to launch a constellation of low earth orbit satellites that will provide low latency high speed broadband connectivity to unserved and underserved communities. Low earth orbits leo are satellite systems used in telecommunication which orbit between 400 and 1 000 miles above the earth s surface.

Nasa s low earth orbit satellites adjust their inclination every year or two to maintain a sun synchronous orbit. Low earth orbit is classed as an altitude of 2 000 kilometers above the earth s surface with an orbital period that stays between 84 minutes and 127 minutes. Though satellites in low earth orbit travel through the uppermost thinnest layers of the atmosphere air resistance is still strong. They move at extremely high speeds and are not fixed in space in relation to the earth.

An omnidirectional antenna was intended to be small enough to be mounted on the planned phone but the low battery power was insufficient to allow the phone s radio waves to reach a satellite in geostationary orbit 35 785 kilometres 22 236 mi above the earth the normal orbit of communications satellites in which the satellite appears. Leo satellites operate from 500 kilometers 311 miles to 2 000 kilometers above the earth s surface. They are used mainly for data communication such as email video conferencing and paging. Objects below approximately 160 kilometers 99 mi will experience very rapid orbital decay and altitude loss.

A low earth orbit leo is an orbit around earth with an altitude above earth s surface of 2 000 kilometers 1 200 mi and an orbital period between about 84 and 127 minutes. How low is low.
