ITU-R INFORME SM.2092 SPANISH-2007積極的服務分配在相鄰或附近的區域對地球勘探衛星服務(被動)相關的影響的研究

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干擾研究中考慮的現有的和規劃中的無線導航衛星業務(空對地)和航空無線導航業務接收機的技術和性能特性

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使用超寬帶技術設備影響無線電通信業務的相關研究

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在射電天文業務中分配在相鄰或鄰近頻段的活動空間業務的影響研究

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 REPORT SM.2092-2007研究涉及到分配的地球探測衛星業務相鄰或鄰近頻段主動服務的影響(被動)

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無用發射的安全業務的保護

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保護無源業務不受無用發射干擾

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在臨近頻段內分配的無源業務和有源業務之間的兼容性分析

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時間和頻率的術語表和定義

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海上導航和無線電通信設備與系統.導航衛星系統(GNSS).伽利略接收設備.性能要求,試驗方法和要求的測試結果

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.
