Error distributions in aircraft position determination


The paper deals with the problems of determining aircraft coordinates. The widely used Gaussian distribution does not make it possible to analyze extremely rare events with certainty. The ICAO- recommended double-exponent distribution does not meet the requirements of accuracy either. It is, therefore, necessary to look for new distributions. The paper gives examples of such distributions as well as examples of solving problems of detecting violations of separation.
