Low Earth Orbit Satellite Names

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.

Low earth orbit satellite names. An eccentric orbit is elliptical with the satellite s distance from earth changing depending on where it is in its orbit. Oneweb has planned a smaller constellation of about 1 000 satellites to achieve the same functionality. Medium earth orbit meo sometimes called intermediate circular orbit ico is the region of space around earth above low earth orbit altitude of 2 000 km 1 243 mi above sea level and below geosynchronous orbit altitude of 35 786 km 22 236 mi above sea level. 1 296 satellites at a height of 379 miles 610.

Due to atmospheric drag satellites do not usually orbit below 300 km 190 mi. The filings lay out a plan to put 3 236 satellites in low earth orbit including 784 satellites at an altitude of 367 miles 590 kilometers. The proposed constellation will include 3 236 satellites in low earth orbit. Why are so many satellites low earth orbit satellites used.

Objects in leo orbit earth between the denser part of the atmosphere and below the inner van allen radiation belt. Equatorial low earth orbits eleo are a subset of leo. Eccentricity refers to the shape of the orbit. With an orbital period of about 100 minutes a satellite can only be in view of a phone for about 7 minutes so the call is automatically handed off to another satellite when one passes beyond the local horizon.

First to help answer this question here s some quick information as to what the leo and geo orbits themselves is in the first place. Iridium satellite constellation an operational constellation of leo satellites for global satellite phone service. Geocentric orbits ranging in altitude from 2 000 km 1 240 miles to just below geosynchronous orbit at 35 786 kilometers 22 236 mi. Geocentric orbits with altitudes below 2 000 km 100 1 240 miles.

In order for a handheld phone to communicate with them the iridium satellites are closer to the earth in low earth orbit about 781 kilometres 485 mi above the surface. Also known as an intermediate circular orbit. A satellite with a low eccentricity orbit moves in a near circle around the earth. New zealand s first commercial satellite antenna for communicating with low earth orbit satellites was officially opened at the awarua satellite ground station near invercargill on monday.

These are most commonly at 20 200 kilometers 12 600 mi or 20 650 kilometers 12 830 mi with an orbital period of 12 hours.
