Those are little leos big leos and mega leos.
Low orbit satellite communication.
How low is low.
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.
A low earth orbit leo is an earth centred orbit with an altitude of 2 000 km 1 200 mi or less approximately one third of the radius of earth or with at least 11 25 periods per day an orbital period of 128 minutes or less and an eccentricity less than 0 25.
They are used mainly for data communication such as email video conferencing and paging.
There is a large variety of other sources that define leo in terms of.
Traditional communication satellites are stationed far higher at roughly.
Deloitte and i are predicting that there will be more than 700 low earth orbit leo high speed data satellites whizzing around the planet by the end of 2020 some of them from a toronto company.
These satellites are used for satellite phones and gps.
If successful this approach will create an optical backbone in space which would be 1 5 times faster than terrestrial fber backbones.
Leo satellites operate from 500 kilometers 311 miles to 2 000 kilometers above the earth s surface.
Most of the manmade objects in outer space are in leo.
Russian communications satellites and the sirius radio satellites currently use this type of orbit.
Low earth orbit satellites.

The satellite moves in an extreme ellipse with the earth close to one edge.
With up to 108 low orbit communications satellites in the constellation leosat wants to be the first to have all the high throughput satellites hts in the constellation interconnected through laser links.
A low earth orbit is an orbit around earth with an altitude above earth s surface of 2 000 kilometers 1 200 miles and an orbital period between about 84 and 127 minutes.
Low earth orbit leo satellites are mainly classified into three categories.
Pisacane 2005 the molniya orbit is highly eccentric.
