Yes, and the Norden sight was said to be able to put a bomb in a pickle barrel.

After final alignment of the pulses, a timing display was switched in and the time delays for each slave visually counted. This could be done accurately because the signals were switched off and a noise free display was obtained. For various reasons, time was not counted in microseconds (as was done in Loran) but in 'Gee units' where one unit was equivalent to 66.66 microseconds. A measurement accuracy of 1 microsecond was achievable, representing a position line accuracy of about 150 meters at best; two such providing a fix accuracy of around 210 meters , although other errors in the system might double this. At longer ranges, 350 miles for example, the error ellipse was about 6 miles by 1 mile. While not remarkable by today's standards, it was revolutionary at the time and far in advance of any other method of fixing.
