This paper describes prototype Aids to Navigation Simulation System (AtoNSiS) that we have recently developed Aids to Navigation (AtoN) training equipment based on the virtual reality technology. To produce an enhanced AtoN simulation experience, three-dimensional (3D) cardinal and lateral buoys are created, and then build up the virtual 3D waterway world according to the guidelines of IALA (International Association of Lighthouse Authorities) in region B. The AtoNSiS have Simulation Module (SM) and Explanatory Module (EM). SM is to learn about the IALA-B system using virtual navigation world varying with environmental factors. EM is to view more detailed marker characteristics using 3D objects. In this work, we present system design concepts, development processes, and simulation experiments of prototype AtoNSiS. Results from tests and evaluations with five subjects provide practical insight on the importance of AtoNSiS.

Among the failure cases of the existing navigation aids, the SW and operating system errors of the RTU, the embedded computer for navigation aids, account for about 10%. The causes of SW errors have an infinite number of cases, and it is impossible to correct them all. In this paper, we proposed a paravirtualized multi-OS Docker container utilization technique as a stable operation technique for smart navigational aids, which have recently increased the amount of computation and complexity of SW services that need to be managed. It is proposed to divide containers according to service type, expected load, and error frequency and load the service.

This study has searched to find a program in order to manage simply and practically use the expelled AtoN database from the AtoN Simulator and to support the idea decision for the AtoN placement. It examines a program that manages AtoN database through the hierarchy structure, history card and endowment with condition same as a scenario. And accomplishes this study's goal owing to realizing AtoN operational software that helps for visual, hearing sense, fixed amount verification upon AtoN placement project. The AtoN operational software contributes not only flexible control like a newly establishment, relocation etc, but also supports idea decision for AtoN placement plan through many functions such as condition search, virtual sailing and fixed amount appraisal result exhibition, etc. Through utilization of this, it is to help upon the presupposition of the impact to ship or sailor about many designs and in addition, upon the judgment of whether or not for the efficiency and appropriation of the design. It is expected to reduce possible failure costs and management costs due to AtoN design and placement plans, because to compare more various designs thru the easier verification method.

As AIS AtoN has worked an essential role for aids to navigation, the World-wide IALA-Net has announced plans to build the system. Systematic beacon network may offer opportunities to make an infrastructure for information service and upgrade AtoN service performance. This paper proposes Aids to Navigation information service network for e-NAV. Network based on AIS is consist of AIS AtoN channels as Real, Synthetic or Virtual AIS AtoN. And inner network is consist of Wireless networks as AIS, WCDMA, WIFI, WIBRO, USN or VSAT. Introducing of various network systems can lead to combine and design aomong land, beacon and service network infrastructures.

이 논문에서는 최근 항해분야에 응용이 시도되고 있는 가상현실(Virtual Reality)이 항해에 유용하게 적용된 연구내용과 결과를 기술하였다. 먼저, VR의 일반적인 기술과 요구사항을 살펴보고, VR을 선박 시뮬레이터에 적용한 연구내용, VR을 항로표지에 적용한 연구내용, VR 에서의 3차원 음향 구현 방법, 그리고 VR 온라인 다중 사용자환경 시스템 구성방법 등을 기술하였다. 검토결과 VR을 항해분야에 적용하는 경우, 보다 현실감 있게 해상의 상황을 항해사에게 전달할 수 있기 때문에 앞으로 응용분야가 폭 넓게 확대될 것으로 예상된다. 특히, 각종 시뮬레이터는 물론, 실시간 계측장비 분야에도 적극 적용하므로써 보다 편리하고 쉽게 항해사가 정보를 획득할 수 있을 것으로 기대된다.

For decreasing the maritime pollution accident of the large material(crude oil, ore and so on) carrier, as we construct the Virtual AtoN AIS utilizing the existing AIS Base Station in the area of major route, passage way and danger or in case of emergency danger, it can help the normal vessel to pass the area without any obstacles and inform the danger elements to AIS. ECDIS and radar of the large carrier.

The paper deals with the design and implementation of Navigational Aids Training Simulator (VR-NATS) by Virtual Reality (VR). To gave interaction and immersible training situation to the user, prototype VR-NATS was developed based on the object-oriented operating system with 3D objects of navigational aids. Using the VR-NATS we created virtual navigational aids. As results from the assessment tests, students can obtain IALA (International Association of Lighthouse Authorities) rules of the navigational aids exactly and quickly comparing with conventional education methods. Thus, we found that he proposed VR-NAT is very effective for the next-generation simulation system.
