本标准规定了我国职业的分类结构、类别、代码及说明。本标准适用于按职业分类的各种普查、调查统计及行政管理和国内外信息交流等。
本标准为船东和船队管理系统(FMS)操作者选择和执行网络管理服务提供概况和指南,它包括:a)一般基础设施的指南,包括宽带网络、数据传输服务;b)船上安装指南,包括应用程序的服务;c)陆上安装指南,包括应用程序、数据库工具。本标准不涉及安全相关系统的要求,例如航海、无线电通信及船舶控制系统。本标准不涉及与FMS相关的环境因素。
本标准适用于按《高速船安全规则》(HSC规则)[IMO MSC.36(63)决议第13章]要求安装在高速船上的探照灯。安装在高速船上的探照灯有助于发现其他船舶、海上结构物、航行障碍物、浮动物体和生物、海岸线及固定航标和浮标。在航行中为驾驶者提供航行安全、避碰以及搜寻救助遇难者等必要的帮助。
本标准适用于安装在高速船上的夜视仪的操作和性能要求及其试验方法,高速船需符合IMO的高速船安全规则(HSC规则)第13章的要求,并且高速船夜视仪应符合IMO MSC.94(72)的性能标准。
GB/T 30287的本部分规定了卫星定位船舶信息服务系统(以下简称系统)的体系结构和功能描述。本部分适用于通过卫星定位技术、采用公众移动通信网络或专用移动通信网络、具有船舶信息服务中心的信息系统,可作为系统设计依据。通过非卫星定位技术、具有船舶信息服务中心的信息系统亦可参照执行。
本标准规定了船舶舱室火灾探测器的分类、选型原则及布置原则。本标准适用于船舶火灾探测系统中火灾探测器的设计选型和布置。
The ITU Radiocommunication Assembly, considering that radar systems can produce interference to digital radio-relay systems (DRRSs) in some situations; that there are two coupling mechanisms by which radiated energy from radar stations may be coupled into radio-relay systems: radar spurious emission in the radio-relay bands; radio-relay system front-end overload (receiver desensitization) caused by the radar fundamental frequency; that the most desirable method of mitigating the interference may be to reduce the spurious emissions at the radar transmitter to a sufficiently low level; that some of the techniques employed by radio-relay system designers to enhance system performance are expected to reduce the susceptibility of these systems to interference from radar transmitters.
The passive radio astronomy service (RAS) is studying natural phenomena producing radio emissions at frequencies fixed by the laws of nature. Primary allocations have been made to various space services in the Earth-to-space direction such as the fixed-satellite service (FSS), radionavigation-satellite service (RNSS), mobile-satellite service (MSS) and broadcasting-satellite service (BSS) in bands adjacent or nearby to bands allocated to the RAS.
The purpose of the Report is to define the public protection and disaster relief (PPDR) objectivesand requirements for the implementation of future advanced solutions to satisfy the operationalneeds of PPDR organizations around the year 2010. Specifically, it identifies objectives, applications, requirements, a methodology for spectrum calculations, spectrum requirements and solutionsfor interoperability
