SYSTEMATIC TRACK RECONSTRUCTION(STR) COMPUTER PROGRAM.
Abstract
The present technique for resolving navigational conflicts involves 'eyeballing' the tracks, and guessing a possible solution. At best, this is not reproducible. The report describes a mathematically consistent method for obtaining the most probable estimate of actual positions from these conflicting records. Physically, the mathematics correspond to sliding the DRTs with respect to one another, rotating them, and stretching them so that a statistical compromise is obtained from the conflicting reports of ship position. As a comprmise, therefore, reconstructed tracks may differ from actual ship movements. The computer program determines a confidence level for each reconstructed track which is a measure of the probability that the actual course differs from the reconstructed track. (Author)
