In this paper a mathematical analysis of the Digital Selective Calling (DSC) system is presented with regard to the occurrence probability of different errors which can cause generation of false distress signals [5,6]. In particular, the kinds of sequences were considered which - in accordance with some ITU recommendations - should indicate "distress", "urgent" and "routine" messages. The DSC system serves within the GMDSS as the only way of sending alert signals by means of terrestial communication [3,4]. However during its use at sea DSC creates many serious problems aspcially those connected with the false alert signal generation [7]. Presently this problem is being carefully monitored and analyzed under auspices of the International Maritime Organization (IMO) and International Telecommunication Union (ITU).
