This article has looked into the role of the magnetic compass in providing navigational safety for ships. The existing requirements of the magnetic compass for safe navigation in case the gyro compass breaks-down and in case of terrorists abusing GPS signals do not solve the problems that occur in everyday life. Therefore, a new rational requirement has been proposed for the accuracy and frequency of deviation adjustment work assuring the safety and cost effectiveness of navigation. Vessel owners and masters have responsibilities to ensure that magnetic compasses are maintained in good working order, are adjusted and accompanied by a table or curve of residual deviations. This article has outlined the most urgent problems for the adjustment of magnetic compasses that apply to all ships irrespective of size and navigation area. The proposed method has been verified experimentally. [ABSTRACT FROM AUTHOR]

The author presents a new perspective on the process of controlling course indicators, to fit with the modern equipment of present day ships, in line with current trends and prospects for its development. The newly proposed measures and methods in this research must address the following issues: the improvement of safety, reduction in routine work and improvement of the navigation services on a ship. This article includes an analysis of requirements and also test results relating to compliance with respect to the course indicators used on commercial vessels. The author presents and justifies the need to introduce changes to the procedures and practices of conduct, updating the current actual situation. The proposed new procedures should have a direct impact on the security of navigation. [ABSTRACT FROM AUTHOR]

The article presents the results of compliance with effects of impact wave course and the resulting orbital motions on the accuracy of the gyrocompass. [ABSTRACT FROM AUTHOR]

In the paper the priority of technical means and methods of navigation at contemporary seagoing ship was discussed. The role of magnetically compass and gyrocompass at the condition of contemporary ship was described. Effectiveness of gyrocompass and magnetically compass from point of navigation and economy was analyzed. The result of analysis is reflected at the recommendation for navigators and managers of ship's company. [ABSTRACT FROM AUTHOR]
