active satellite
Technical term in aerospace and telecommunications; a satellite that carries its own power source and actively transmits signals, as opposed to a passive satellite that merely reflects them.
An active satellite transmits radio waves on its own.
Passive satellite; contrasts with 能動衛星 in that it only reflects signals without active transmission.
Compound of 能動 (active) and 衛星 (satellite), likely a calque from English 'active satellite'.
