• d = radius of the orbit
• g₀ = 398600.5 km³/s²

Here,  g₀ is the Standard Gravitational Parameter of Earth

g₀ = G (M+m) ≈ GM = 398600.5 km3/s2

where,

• G is the Gravitational Constant
• M & m are the Masses of the two objects (i.e., earth and satellite in this calculator)

Note: The radius of a MEO orbit is approximately between 2000 km and 35786 km. So, the satellites in the MEO orbit are placed in between the given range.

For Example:

Consider the radius of the orbit, d = 5000 km

Then, the orbital period of the satellite, T = 2πd^3/2 / √ g₀

= 2*(22/7)*5000^3/2 / √ 398600.5

= 3519.98427556 sec
