Satellite Earth Stations and Systems (SES); Satellite mobile Aircraft Earth Stations (AESs) operating in the 11/12/14 GHz frequency bands; Harmonised Standard for access to radio spectrum

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).
