SJ/T 11588-2016BDS/GPS射频与基带一体化模块性能要求与测试方法

本标准规定了BDS/GPS射频与基带一体化模块(以下简称模块)的性能要求和测试方法。本标准适用于具有定位、授时和短报文通信功能的BDS/GPS射频与基带一体化模块(包括RNSS模块和RDSS模块)的设计、研制、生产和检测。

ITU-R INFORME SM.2092 SPANISH-2007积极的服务分配在相邻或附近的区域对地球勘探卫星服务(被动)相关的影响的研究

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.

ITU-R M.1477-20001559-1610MHz干扰研究中考虑的现有的和规划中的无线导航卫星业务(空对地)和航空无线导航业务接收机的技术和性能特性

There is a long history of reserving a portion of the interference link budget for a margin in order to ensure that theradionavigation service is protected. These margin values typically lie in the range of 6 to 10 dB, or more. Furthermore,there is am

ITU-R REPORT SM.2057-2005使用超宽带技术设备影响无线电通信业务的相关研究

This Report considers interferences from devices using ultra-wideband (UWB) technology on radiocommunication services. As a main objective, it evaluates UWB e.i.r.p. density required for the protection of radiocommunication services.This Report also includes laboratory and field measurements on the impact of devices using UWB technology on radiocommunication services.

ITU-R REPORT SM.2091-2007在射电天文业务中分配在相邻或邻近频段的活动空间业务的影响研究

ITU-R REPORT SM.2092-2007研究涉及到分配的地球探测卫星业务相邻或邻近频段主动服务的影响(被动)

The passive Earth exploration-satellite service (EESS) (passive) is focussing on the reception ofnatural emissions at much lower levels that are generally used in other radiocommunicationsservices. Therefore, sensors are generally more susceptible to interference from unwanted emissionsof active services.

ITU-R SM.1535-2001无用发射的安全业务的保护

For the purposes of this Annex, electromagnetic noise or noise is defined as all electromagneticenergy from both intentional and unintentional radiators, except from a desired signal for a specificsystem of interest.

ITU-R SM.1542-2001保护无源业务不受无用发射干扰

that it is desirable that unwanted emissions of new stations in any radio service should notrender existing stations, operating in accordance with the Radio Regulations (RR) in those or otherservices, unable to operate effectively

ITU-R SM.1633-2003在临近频段内分配的无源业务和有源业务之间的兼容性分析

The following general methodology defines a systematic means for deriving mutually acceptablecompatibility criteria between operators of active and passive services operating in their allocatedbands. The flow diagram (Fig. 1) summarizes the methodolog

ITU-R TF.686-3-2002时间和频率的术语表和定义

The terms listed in Annex 1 are taken from relevant ITU-R and ITU-T Recommendations, ITU-R Handbooks, the International Vocabulary of basic and general terms in Metrology (VIM) published by International Organization for Standardization (ISO), the Glossary of Time and Frequency Terms of the National Institute of Standards and Technology (NIST), and other noted references. Annex 1 also includes anumber of related telecommunication terms in general usage in the field of frequency and time. Two types of terms are presented; those typically used within the standard-frequency and time-signal services and those in more general use, but specifically applicable to this field.

BS EN 61108-3-2010海上导航和无线电通信设备与系统.导航卫星系统(GNSS).伽利略接收设备.性能要求,试验方法和要求的测试结果

This part of IEC 61108 specifies the minimum performance standards, methods of testing andrequired test results for Galileo shipborne receiver equipment, based on IMO resolutionMSC.233(82), which uses the signals from the Galileo Global Navigation Satellite System inorder to determine position. It takes account of the general requirements given in IMOresolution A.694(17) and is associated with IEC 60945. When a requirement in this standardis different from IEC 60945, the requirement in this standard takes precedence. It also takesaccount, as appropriate, of requirements for the presentation of navigation-related informationon shipborne navigational displays given in IMO resolution MSC.191(79) and is associatedwith IEC 62288.A description of the Galileo Open Service and Safety of Life Service is given in the Galileointerface control documents (see Bibliography). This receiver standard applies to navigation inocean waters for the open service and harbour entrances, harbour approaches and coastalwaters for the Safety of Life service, as defined in IMO resolution A.953(23).All text of this standard, whose meaning is identical to that in IMO resolution MSC.233(82), isprinted in italics and the resolution and paragraph numbers are indicated in brackets i.e.(M.233/A1.2).The requirements in Clause 4 are cross-referenced to the tests in Clause 5 and vice versa.
