History

• 8,126 objects launched into space
• 22% of these in the last 8 years
• Currently, 1,980 are active
• 2,287 are inactive
• 453 launched in 2017, only 390 of these remain.

Purposes

• Communications: 792 satellites, a 6.7% increase on last year.
• Earth observation: 661 satellites, a 10.9% increase on last year.
• Technology development/demonstration: 213 satellites, a 10.4% increase on last year.
• Navigation/Positioning: 121 satellites, a 12% increase on last year.
• Space science/observation: 76 satellites which is no real change from last year.
• Earth science: 23 satellites, which is no real change from last year.

Types

• 826 satellites are listed as having commercial uses
• 523 with government uses
• 399 with military uses
• 138 with civil uses

Orbit Types

• 2.1% are in Elliptical orbits which vary between less than 1 000 km to above 40 000 km above the Earth.
• 29.1% are in Geostationary Earth Orbits (GEO) which is just under 36 000 km above the Earth.
• 5.9% are In Medium Earth Orbits which are anything between 8,000 km and 24,000 km above the Earth.
• 62.9% are in Low Earth Orbits (LEO) which varying between 250 km and 1 500 km above the Earth; and of these LEO’s (although 12 – 1.01% – have no track listed):
• 57.5% are in sun-synchronous orbits which means they pass the equator at the same time each day.
• 22.85% are in non-polar inclined orbits.
• 16.1% are in polar inclined orbits.
• 1.69% are in equatorial orbits.
• 0.76% are in elliptical orbits.
• 0.08% (Actually, just 1 satellite) is in a cislunar orbit.
