In many practical situations in the field of navigation, it has been noticed that the probability distribution of measured errors has a shape which has considerable departures from that of the normal distribution. These departures are particularly noticeable in the 'tails' of the distribution of practical cases, which are often higher than those of the corresponding normal distributions (see, for example, 'Is the gaussian distribution normal', W/Cdr.
