SUMMARY
The discussion focuses on calculating the height of communications satellites above Earth's surface, specifically those in a geostationary orbit that completes one rotation every 24 hours. The relevant equation is derived from the formula GM/(4π²)T², where G represents the gravitational constant, M is the mass of the Earth, and T is the orbital period. Participants clarify that the mass (M) in the equation refers to the mass of the Earth, essential for determining the satellite's orbit radius.
