Opis:
Standard ECDIS configuration doesn’t foresee interaction with Digital Selective Calling (DSC) device. We propose a reasonable way to eliminate the drawbacks of existing VHF radiotelephony using DSC and obtain new advantages in communication and navigation in the frame of existing conventional installations. The proposed innovation is based on ECDIS software updating and the interconnection to DSC equipment. ECDIS modernization would get rid a navigator of the routine procedures and handling with abstract data replacing them by understandable actions on ECDIS display. The proposed integration gives new abilities for smart addressed VHF/DSC communication by estimating the current navigational situation around the ship that is especially important in congested ports, waterways and poor visibility regarding human factor. The proposed modernization retains in operation all standard DSC and ECDIS functions and provides full compatibility with commonly used non-integrated equipment. Financial expenses to its implementation for ship-owner are minimal due to only software updating and standard cabling.

Opis:
Audio watermarking (AW) technology is considered for stealthy information embedding directly into audio signal. Inherent in analog radiotelephone channel interferences against watermarks are analyzed. Robust encoding/decoding algorithms are presented and appropriate project of AW system named as Automatic Radio Telephone Identification System (ARTIS) is proposed. Experimental results for the practical VHF radio channel are presented. Relating on processing complexity the designed system enables imperceptibly transmit data on a rate up to 260 bit/sec in the standard VHF radio channel. ARTIS provides the full compatibility with the existing radio installation, and doesn’t require replacement of standard VHF transceivers and operational procedures. Besides, automatic identification the system may be used in the special applications, for example, under the threat of terrorist attack; generally contributes to navigation safety and information security.
