Yes there are, the type 11 on subs are 11 seconds of arc.( I am sure they are better now my info 1978) But I should have said that the bearing taker with tel scope can read to the decimal of one degree. The plotter with a protractor can only plot to about a 1/3 of a degree. The USS in Intrepid CVS11 got out of the Yards with a one and half degree compass error, aligned with a bad azumuth circle I found the error to be 1.5 she got pin point fixes in a training evaluation in GTMO. Cuba, she than ran the forac range for gyro error and they found it to be 1.65 Sounds unheard of, but Naval ships can't should go to extreme for haphazard waters. If interested in more inline imfomation about ship piloting.See "Byron Franklin QMCM" on the internet.
