Sistemet dhe Stacionet Satelitore në Tokë (SES); Stacionet Tokësore të Mjeteve Fluturuese që punojnë nën 3 GHZ nën shërbimin Satelitor Aeronautik të Lëvizshëm (AMSS)/Shërbimi Satelitor i Lëvizshëm (MSS) dhe/ose Satelit Aeronautik i Lëvizshëm në Shërbimin e Itenerarit (AMS(R)S)/ Shërbimi Satelitor i Lëvizshëm (MSS)

Satellite Earth Stations and Systems (SES); Aircraft Earth Stations (AES) operating below 3 GHz under the Aeronautical Mobile Satellite Service (AMSS)/Mobile Satellite Service (MSS) and/or the Aeronautical Mobile Satellite on Route Service (AMS(R)S)/Mobile Satellite Service (MSS)

Scope

The present document specifies certain minimum technical performance requirements of Aircraft Earth Station (AES)
equipment with both transmit and receive capabilities for operation in the Aeronautical Mobile Satellite Service
(AMSS)/Mobile Satellite Service (MSS), and/or in the Aeronautical Mobile Satellite on Route Service
(AMS(R)S)/Mobile Satellite Service (MSS), in the frequency bands given in table 1.
Table 1: Aeronautical Mobile Satellite Service (AMSS)/Mobile Satellite Service (MSS),
and/or Aeronautical Mobile Satellite on Route Service (AMS(R)S)/
Mobile Satellite Service (MSS) frequency bands
AMSS/MSS and/or AMS(R)S/MSS frequency bands
AES transmit 1 610 MHz to 1 626,5 MHz
AES receive 1 613,8 MHz to 1 626,5 MHz
AES receive 2 483,5 MHz to 2 500 MHz
AES transmit 1 626,5 MHz to 1 660,5 MHz
AES receive 1 525 MHz to 1 559 MHz
AES transmit 1 668 MHz to 1 675 MHz
AES receive 1 518 MHz to 1 525 MHz
AES transmit 1 980 MHz to 2 010 MHz
AES receive 2 170 MHz to 2 200 MHz
The technical requirements in the present document are in two major categories:
• emission limits: to protect other radio services and systems from harmful interference generated by the AES
in normal use;
• AES Control and Monitoring Functions (CMF): to protect other radio services and systems from unwanted
transmissions from the AES. The CMF in each AES is capable of answering to commands from the Network
Control Facilities (NCF) for its supporting satellite network.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN MES transmitting in the 1 610 MHz to
1 626,5 MHz band or the 1 980 MHz to 2 010 MHz band are contained in ETS 300 735 [4]; these
requirements are also applicable to AES transmitting in those bands.
An AES may be subject to additional or alternative requirements in other standards depending on its functionality, in
particular if it supports a service which is considered a justified case for regulation of terminal equipment interworking
via the public telecommunications network. An AES will also be subject to additional airworthiness certification
requirements.
