DANSK DS/EN 301 473 V2.1.2 PDF

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 three major categories: The technical requirements in the present document are in three 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; • receiver performance specifications: to enable reception of a wanted signal in presence of other high power signals on the adjacent channel and/or adjacent band. NOTE 1: 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 ETSI 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. The present document is intended to cover the provisions of Directive 2014/53/EU [6] (RE Directive) article 3.2 which states that "Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the RE Directive [6] may apply to equipment within the scope of the present document.
