What is Medium Earth Orbit?
Advertisements
उत्तर
- If the height of the satellite orbit above the earth’s surface is between 2000 km and 35780 km, the orbits are called medium earth orbits.
- In these orbits, the satellites complete one revolution in 2 to 24 hours.
- The geostationary satellites cannot be used in the study of polar regions.
- For this purpose, elliptical medium earth orbits passing over the polar region are used. These orbits are also called as polar orbits.
