Where must satellites be positioned relative to the observer and the sun for optimal visibility?
Answer
High enough above the horizon but low enough to catch the sun's rays while the observer is in darkness
Visibility requires a sweet spot: high enough to be seen above obstructions but low enough in the atmosphere to catch the sunlight when the ground observer is experiencing twilight or darkness.
