That is, if CEP is n metres, 50% of shots land within n metres of the mean impact, 43.7% between n and 2n, and 6.1% between 2n and 3n metres, and the proportion of shots that land farther than three times the CEP from the mean is only 0.2%. CEP is not a good measure of accuracy when this distribution behavior is not met.
Each array detects an impulsive event such as motor/rocket launch and determines the line of bearing from the array to the launch site. The lines of bearing from each array are transmitted via radio link to a central point where the results are combined to establish the location of the firing point through triangulation.
The course line is selected by turning an "omni bearing selector" or "OBS" knob usually located in the lower left of the indicator. It then shows the number of degrees deviation between the aircraft's current position and the "radial" line emanating from the signal source at the given bearing. This can be used to find and follow the desired radial.
These detectors listen to the sounds of passing trains and identify sounds that correspond with defective bearings. [2] If a sound that is similar to the noise made by a defective bearing is identified, the car with the noise should be removed from the train at its next stop to be inspected and repaired if necessary.
The process of keeping track of where the ship was likely to be was called rangekeeping, because the distance to the target—the range—was a very important factor in aiming the guns accurately. As time passed, train (also called bearing), the direction to the target, also became part of rangekeeping, but tradition kept the term alive.
