  • Orbit satellites them
    Types of orbits
    GEO (Geosynchronous Earth Orbit): circular equatorial geosynchronous orbit
    - Revolution period: 23 h 56 m 4.091 s
    - Average altitude: 35,786 km
    LEO (Low Earth Orbit): circular orbit of low altitude
    - Typical altitude: 500 - 1500 km
    - Revolution period 1h 30m - 2h
    MEO (Medium Earth Orbit): circular orbit of average altitude
    - Typical altitude: 10,400 km
    - Revolution period of six hours
    HEO (Highly Elliptical Orbit): strongly elliptical orbit
    - Inclined elliptical orbit
    - Lowland perigee
    notable case: Molniya orbit
    Perigee: 1,000 km alt. Apogee: 39,000 km alt.
