I am conversant with commercial INS and old military INS (LN3) and know that
the best alignment occurs when the a/c is stationary. Now my question.
How is the INS aligned at sea on a carrier that is moving at 30kts? Does the
ground crew start an alignment below decks prior to bringing the a/c up for
a launch? Also does the Captain have to realign heading on the catapult to
ensure proper heading reference or is there a slaved compass system in naval
military fighters?
