The nearer to earth the faster the required orbital velocity.
Satellite orbit height in miles.
A satellite at this height takes 12 hours to complete an orbit.
The region below medium orbits is referred to as low earth orbit leo and is about 160 to 2 000 kilometres 99 to 1 243 mi above earth.
As the satellite moves the earth rotates underneath it.
A geosynchronous orbit is a high earth orbit that allows satellites to match earth s rotation.
Iridium satellites orbit at about 780 km 480 mi.
Medium earth orbit meo satellites are closer to earth.
Included in this category are geostationary gso satellites which remain in orbit above a fixed spot on earth.
Geosynchronous orbits geo geo satellites orbit earth at an altitude greater than 22 223 miles 36 000 kilometers and their orbital period is the same as earth s rotational period.
Medium earth orbit meo.
As the satellite moves the earth rotates underneath it.
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.
A satellite at this height takes 12 hours to complete an orbit.
The semi synchronous orbit is a near circular orbit low eccentricity 26 560 kilometers from the center of the earth about 20 200 kilometers above the surface.
Each satellite circles the earth twice a day.
To maintain an orbit that is 22 223 miles 35 786 kilometers above earth the satellite must orbit at a speed of about 7 000 mph 11 300 kph.
The semi synchronous orbit is a near circular orbit low eccentricity 26 560 kilometers from the center of the earth about 20 200 kilometers above the surface.
Located at 22 236 miles 35 786 kilometers above earth s equator this position is a valuable spot.
Geocentric orbits ranging in altitude from 2 000 km 1 240 miles to just below geosynchronous orbit at 35 786 kilometers 22 236 mi.
Also known as an intermediate circular orbit.
Lower orbits also aid remote sensing satellites because of the added detail that can be gained.
Gps satellites fly in medium earth orbit meo at an altitude of approximately 20 200 km 12 550 miles.
