The present document specifies certain minimum technical performance requirements of Aircraft Earth Station (AES) equipment with both transmit and receive capabilities for provision of aeronautical mobile satellite service, in the frequency bands given in table 1. Table 1: Frequency bands for the AES equipment specified in the present document Mode of Operation Frequency Band AES transmit 14,00 GHz to 14,50 GHz AES transmit 12,75 GHz to 13,25 GHz AES receive 10,70 GHz to 12,75 GHz The AES has the following characteristics: • These AESs are equipment for installation on aircraft. • The AESs transmit in the 14,00 GHz to 14,50 GHz band receive within the range from 10,70 GHz to 12,75 GHz ("14 GHz"), referred to as "14 GHz AES" in the present document, are operating in one or more frequency ranges of the Fixed-Satellite Service and Mobile-Satellite Service. • The AESs transmit in the 12,75 GHz to 13,25 GHz band receive within the range from 10,70 GHz to 12,75 GHz ("13 GHz"), referred to as "13 GHz AES" in the present document, are operating in one or more frequency ranges of the Fixed-Satellite Service. NOTE 1: When the term "AES" used in the present document without stating 13 GHz AES or 14 GHz AES, it is a reference to both 14 GHz AES and 13 GHz AES. • The AES could consist of a number of modules from the antenna subsystem to the user interfaces. • The AES uses linear polarization. • The AES system uses digital modulation. • The 14 GHz AES operates through a GSO satellite at least 3° away from any other geostationary satellite operating in the same frequency band and covering the same area. • The 13 GHz AES operates with a GSO satellite network whose frequency assignments are from the List of Appendix 30B of the Radio Regulations. • The antenna of the AES is directional, with means of tracking the satellites, which can be achieved by using either an active phase array or reflective type configuration. • These AESs are operating as part of a satellite network used for the distribution and/or exchange of information between users. • These AESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document. • When on the ground, the 14 GHz AES does not transmit at elevation angles below 7° with respect to the local horizontal plane, except at locations where transmissions below 7° are permitted by the local Administration; (the minimum elevation angle is also limited as per clause 4.2).
