Introduction
An AES to be effectively used on board an aircraft will also be subject to airworthiness approval. This approval will
refer to additional requirements (e.g. ISO 7137 equivalent to EUROCAE ED-14D and RTCA DO-160D [1]).
Foreseeable evolution of the GNSS (i.e. Galileo or GPS L5) would result in the coming years in specific requirements
to protect the use of the GNSS signals on board aircraft. Therefore these new GNSS frequency bands may require
different protection than currently stated in the present document.

1 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 1 980 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.
