Satellite Orbits

Learning Objective: to calculate the orbital period of satellites in various altitude earth orbits.

There are basically 3 major types of satellite orbits, LEO, MEO and GEO.

LEO: Low Earth Orbit
These orbits include;
The International Space Station. The station flies at an average altitude of 248 miles (400 kilometers) above Earth. It circles the globe every 90 minutes at a speed of about 17,500 mph (28,000 kph).

Using the formulas T = [r^3 / GMe]^1/2 and c= 2 pi* r, use the orbital altitude to confirm the period of the orbit and the orbital speed.
