Why carrier fighter control differed from the RAF system

How much did Royal Navy fighter control borrow from the RAF system used in the Battle of Britain?

It shared principles but evolved differently because a carrier's radar sits on the target; the navy needed airborne patrols, while the RAF could exploit extra distance to scramble fighters from land.

RAF sector control detected raids beyond the defended target and could scramble interceptors through the space between radar stations and cities. A carrier carried both radar and target together, leaving much less time to launch and climb, so the Royal Navy emphasised standing combat air patrols and continuous flight operations. The U.S. Navy first adapted fighter-control lessons brought from Britain and then borrowed more naval practice through USS Robin. Neither system was inherently better: each reflected its warning geometry, maintenance burden, fuel supply, and defended objective.
