In the immediate post-war period, ships were fitted with basic gyro compasses (typically AP5005) plus a transmitting magnetic or gyro-magnetic compass (ATMC5/AGMC6) for emergencies. Vertical attitude reference data came from wholly separate stabilisers (Gyro Stabiliser Type 1-12). Radio navaids were limited to the early Decca sets (QM10) and MF DF (FM12), with widespread use of astro navigation (by hand-held sextant), plus a 1930's vintage ARL table.
