Which statement about a crosslink in a satellite constellation is true?

• A. It is a ground-station to satellite link.
• B. It is a satellite to ground link.
• C. It is a satellite-to-ground link.
• D. It is a satellite-to-satellite link that relays data.

Answer: (C)

A crosslink is an inter-satellite communication path. It connects one satellite directly to another, letting data be relayed from satellite to satellite across the constellation without always going down to a ground station. This capability is what enables a network to route information efficiently, extend coverage, and maintain links even when a ground station isn’t in view.

Because of that, the statement that describes a crosslink as a satellite-to-satellite link that relays data is the true one. Links involving ground stations—whether ground-to-satellite or satellite-to-ground—are separate types of connections, not crosslinks between satellites.
