Low Earth Orbit Satellite Latency

Depending on the type of orbit i e distance of the satellite and therefore the time taken to travel will vary.

Low earth orbit satellite latency. Since 2016 o3b streaming low latency high speed internet connectivity to remote areas from medium earth orbit meo has become an integral part of ses business plan. At about 35 000 kilometers 22 000 miles above the earth s surface this type of orbit was first used in 1964 for nasa s syncom iii an experimental satellite for communications aboard the delta d rocket. Oneweb says a test of its low earth orbit satellites has delivered broadband speeds of more than 400mbps with average latency of 32ms. The tests which took place in seoul south korea represent.

Sixteen meo satellites currently complement ses fleet of over 50 geos but the operator plans bold future steps in meo. But it does come with its own challenges. The latency is unaffected by the frequency band of the link. That s adequate for broadcasting but is a barrier to real time two way communication.

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. Proliferated leo the building of large constellations of small satellites in low earth orbit is an essential strategy for achieving this resilience. High orbit systems by contrast have a median latency of nearly 600 milliseconds for a round trip. By stephanie mlot june 15 2020.

To date spacex has launched about 650 of its version. But not all satellites were created equal. There is a large variety of other sources that define leo in terms of. The federal communications commission doesn t believe low earth orbit satellite providers can deliver internet service while keeping latency below 100ms.

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. Unfortunately due to the curvature of the earth a geostationary satellite cannot provide continuous service above or below.
