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. WebThe arc measure is equal to the central angle that intercepts it. Since line CA is a diameter, it is equal to 180 degrees, so if you add the measures of angles DPA and DPC, it will equal 180 degrees. Since the measure of DPA is 60 degrees, DPC is equal to 120 degrees.
