Autonomous And Remote Navigation Trial Project
Autonomous and Remote Navigation Trial Project (ARNTP, a-Navigation Trial Project) is the trial of Maritime Autonomous Surface Ship, maritime autonomous surface ships (MASS) in commercial operations hold within 2020 in three different sea water areas of Russia. Dedicated to the trial, three ships belonging to three shipping companies were duly fitted with the required technological equipment, the proper Remote Control Centres were installed by the involved shipping companies. The trial was supported by the federal authorities of Russia who considered and approved necessary legal requirements and rules for the project to follow. The results of the project proved the effectiveness of the technologies used and initiated the nationwide experiment on use of autonomous ships under the Russian flag by any shipping company. Mission The project aimed to establish technical and legal conditions for the wide operation of Autonomous cargo ship, Maritime Autonomous Surface Ship (MASS). T ...

Maritime Autonomous Surface Ship
Autonomous cargo ships, also known as autonomous container ships or maritime autonomous surface ships (MASS), are Unmanned surface vessel, crewless vessels that transport either Shipping container#Intermodal freight containers, containers or bulk cargo over navigable waters with little or no human interaction. Different methods and levels of autonomy can be achieved through monitoring and remote control from a nearby manned ship, an onshore control center or through artificial intelligence and machine learning, letting the vessel itself decide the course of action. As of 2019, several autonomous cargo ship projects were in development, a prominent one being the construction of the , which was initially scheduled to enter trials in 2019 and operations in 2020. In Russia, a group of companies under the umbrella of Industry Association MARINET initiated Autonomous and Remote Navigation Trial Project, the Autonomous and Remote Navigation Trial Project. Within the framework of the projec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STCW Convention
International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) sets minimum qualification standards for masters, officers and watch personnel on seagoing merchant ships and large yachts. STCW was adopted in 1978 by the International Maritime Organization (IMO) conference in London, and entered into force in 1984. The Convention was significantly amended in 1995 and 2010 enter into force on 1 January 2012. The 1978 STCW Convention was the first to establish minimum basic requirements on training, certification and watchkeeping for seafarers on an international level. Previously the minimum standards of training, certification and watchkeeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result, minimum standards and procedures varied widely, even though shipping is extremely international by nature. The Convention prescribes minimum standards relatin ...

SOLAS Convention
The International Convention for the Safety of Life at Sea (SOLAS) is an international maritime treaty that sets minimum safety standards in the construction, equipment and operation of merchant ships. The International Maritime Organization convention requires signatory flag states to ensure that ships flagged by them comply with at least these standards. The current version of SOLAS is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980. , SOLAS 1974 has 167 contracting states, which flag about 99% of merchant ships around the world in terms of gross tonnage. SOLAS in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships. Signatories The non-parties to SOLAS 1974 include numerous landlocked countries (for obvious reasons), as well as El Salvador, Micronesia and East Timor. Some others including Bolivia, Lebanon and Sri Lanka, all considered flag of convenience states, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closed-circuit Television
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or Mesh networking, mesh wired or Wireless, wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV"). Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head. Video surveillance has generated significant debate about balancing its use with individuals' right to privac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microwave Transmission
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplex eight telephone channels over long distances. A link across the English Channel ...

Code-division Multiple Access
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. It can be also used as a cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iridium
Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal (after osmium) with a density of as defined by experimental X-ray crystallography. It is one of the most corrosion-resistant metals, even at temperatures as high as . However, corrosion-resistance is not quantifiable in absolute terms; although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable, whereas gold dust is not flammable but can be attacked by substances that iridium resists, such as aqua regia. Iridium was discovered in 1803 among insoluble impurities in natural platinum. Smithson Tennant, the primary discoverer, named it after the Greek goddess Iris, personification of the rainbow, because of the striking and diverse colors of its salts. Iridium is one of the rarest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless
Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Private Network
A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. The benefits of a VPN include increases in functionality, security, and management of the private network. It provides access to resources that are inaccessible on the public network and is typically used for remote workers. Encryption is common, although not an inherent part of a VPN connection. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely. Types Virtual private networks may be classified into several categories: ;Remote ac ...
