Earth central angle
Webwhere Q is the number of satellite orbits that correspond to one rotation of Earth (the repetition factor). ψ0 and φ0 are, by definition, the target’s latitude and longitude when θ = 0. Let A be the angle between (ψ, φ) and (ψE, φE). This is the angle that needs to be smaller than the cap angle α if the satellite is to detect the target. Webcircumference, central angles, arc length, and scale factor. Background. This problem is part of a series that applies mathematical principles in NASA’s human spaceflight. The International Space Station (ISS) is an internationally developed research facility and is the largest human-built satellite in Earth’s orbit. It
