24、documentThe present document allows the choice ofeither a class A Control and Monitoring system or a class B Control andMonitoring system. The class B system is more suitable for networks comprising very many terminals.The determination ofthe parameters ofthe user earth stations using a given geo-st

The levels,however, do not cover extreme cases which may occur in any location but with a low probability ofoccurrence.The present document may not cover those cases where a potential source ofinterference which is producingindividually repeated transient phenomena or a continuous phenomenon is

31、(2006-02)The present document applies to Very Small Aperture Terminals (YSATs) which have the following characteristics: The YSAT is operating in one or more frequency ranges in the part ofthe following bands allocatedexclusively to the Fixed Satellite Services (FSS):14,00 GHz to 14,25 GHz (earth-to

32、-space);12,50 GHz to 12,75 GHz (space-to-earth);or in the shared parts ofthe following bands, allocated to the FSS and Fixed Services (FS):14,25 GHz to 14,50 GHz (earth-to-space);10,70 GHz to 11,70 GHz (space-to-earth). The YSAT uses linear polarization. The YSAT operates through a geostationary sat

33、ellite at least 30away from any other geostationary satelliteoperating in the same frequency band and covering the same area. The YSAT antenna diameter does not exceed 3,8 m, or equivalent effective area. The YSAT is either:a transmit only YSAT: designed for transmission only of radio-communications

34、 signals in any of thefrequency bands (earth-to-space) specified above; ora transmit and receive YSAT: designed for transmission and reception ofradio-communications signalsin any ofthe frequency bands specified above; ora receive only YSAT: designed for reception only ofradio-communications signals

35、 in any ofthefrequency bands (space-earth) specified above. The YSAT is designed usually for unattended operation. The YSAT is operating as part ofa satellite network (e.g. star, mesh or point-to-point) used for the distributionand/or exchange ofinformation between users. The transmit-only and trans

36、mit-and-receive YSAT is-controlled and monitored by a Centralized Control andMonitoring Function (CCMF). The CCMF is outside the scope ofthe present document.The present document applies to the YSAT with its ancillary equipment and its various terrestrial ports, and whenoperated within the boundary

39、 state: radio state in which the VSAT may transmit and does not transmit any carrierNOTE I: The phrase “the VSAT may transmit“ means that all the conditions for transmission are satisfied (e.g. in astate where transmissions are permitted and no failure detected).NOTE 2: The existence ofa “Carrier-of

40、f radio state depends on the system oftransmission used. For VSATsdesigned for continuous transmission mode there may be no “Carrier-off radio state.carrier-on radio state: radio state in which the VSAT may transmit and transmits a carrierCentralized Control and Monitoring Functions (CCMF): set offu

43、d by the applicant.NOTE: The applicant may declare different values ofEIRPmax and EIRPnom for each combination ofoccupiedbandwidth and transmission parameters (see clause 4.1.3).emissions disabled radio state: radio state in which the VSAT must not transmit a carrierNOTE: This radio state only appli

44、es in certain CMF states as defined in clause 4.1.4. (e.g. before systemmonitoring pass, before the control channel is received, when a failure is detected, when the VSAT iscommanded to disable). The “Emissions disabled“ radio state requires lower unwanted emissions than the“Carrier-off radio state.
