Results of Location Service Measurements for CCDS Applications

In this paper the unique coastal cellular distress system (CCDS), based on a cellular phone network was proposed. The concept, functional properties and services of this system were described. The problem of the location service (LCS) at sea was presented. The geographical location accuracy of a mobile phone in a coastal sea area is analysed. Special measurement system and software application, designed for the field trial is also presented. The measurement results of LCS quality at sea are presented. Finally, the integration of cellular network based system and Search And Rescue service (SAR) was discussed.
