Orbit Period Tool

The orbit period tool can covert between orbit height and radius and calculate the associated period. The parameters are:

• $h=$ height of satellite $(\mathrm{km})$

• $R=$ radius of orbit $(\mathrm{km})$

• $T_P=$ period of circular orbit (minutes)

The equations are:

$$R=R_e+h$$

Where $R_e=6378.145\mathrm{km}$.

Then the period in seconds can be calculated using:

$$P_S=2\pi \sqrt{\frac{R^3}{\mu }}$$

Where $\mu =398600.4418{\mathrm{km}}^{\wedge }3/{\mathrm{s}}^{\wedge }2$.
