SUMMARY
The discussion centers on the application of the Vis Viva equation in determining the orbital speed of a satellite in elliptical orbits. It confirms that the relative velocity calculated by the Vis Viva equation is equivalent to the orbital speed of the satellite. In elliptical orbits, the Vis Viva equation provides the orbital velocity Vo, which is distinct from the circular tangential velocity Vt. The relationship between circular tangential velocity, orbital speed, radial speed, and flight path angle is also validated, establishing that Φ = tan-1(r_dot/Vt).
