700/700D SYSTEM REFERENCE – SEE BELOW……………………………………………………………….
The Cobham AVIATOR 700D system is engineered to take advantage of the latest technologies, such as, SwiftBroadband for increased reliability and connectivity.
The SwiftBroadband Background Data and Standard Voice channel allow users to access a shared data channel and a compressed high-quality voice channel at the same time.
The Aviator 700/700D System is a mounted Aeronautical Communication System supporting simultaneous voice and data communication though Inmarsat BGAN satellite service.
The standard 700/700D system components consist of the following Items:
 SDU (Satellite Data Unit) 405035A or 405035A-THD (TT-5035A or TT-5035A-THD)
 HPA (High Power Amplifier) 405014A or 405014A-THD (TT-5014A or TT-5014A-THD)
 SBU (Satellite Broadband Unit) 405040A or 405040A-THD (TT-5040A or TT5040A-THD)
 Type-F DLNA (Diplexer and Low Noise Amplifier) 405013A (TT-5013A)
 HGA (High Gain Antenna) e.g. 405007A (TT-5007A-THR)
 RF-Splitter 405038A-003 (TT-5038A-003)
 RF-Coupler 405038A-004 (TT-5038A-004)
AVIATOR 700D is an Inmarsat SwiftBroadband HGA (Class 6) System supporting:
  • Single Channel SwiftBroadband
  • Circuit-switched standard voice
  • Background IP up to 432 kbps
  • Streaming IP at 8/16/32/64/128 kbps
  • SB X-Stream services
  • ISDN service or 3.1 kHz audio
  • Inmarsat Satellite Land Earth Station – RAN Cobham AVIATOR
Description of Equipment: The 5035A/5035A-THD Satellite Data Unit (SDU), the 5014A/5014A-THD High Power Amplifier (HPA), the 5040A/5040A-THD Satellite BGAN Unit (SBU) and the 405013A Type F Diplexer and Low Noise Amplifier (DLNA) supports the Swiftbroadband aeronautical satellite communications service.
The transceiver meets the applicable requirement of RTCA/DO-210D “Minimum Operational Performance Standard for Geosynchronous Orbit Aeronautical Mobile Satellite Services (AMSS) Avionics”.
The AVIATOR 700/700D system are comprised of four units:
  • The 5035A/5035A-THD Satellite Data Unit (SDU),
  • the 5014A/5014A-THD High Power Amplifier (HPA),
  • the 5040A/5040A-THD Satellite BGAN Unit (SBU) and
  • the 405013A Type F Diplexer and Low Noise Amplifier (DLNA).
The 5040A/5040A-THD (SBU) & The 5035A/5035A-THD (SDU) supports Inmarsat SwiftBroadband signals using BPSK, QPSK and 16QAM.The SDU/SBU signals are combined and amplified for transmission by the 5014A/5014A-THD (HPA).
The AVIATOR 700/700D is a unique multi-channel solution.
It combines global voice, fax and data capabilities of the Inmarsat Classic Aero, SwiftBroadband and Swift64 service.
The AVIATOR 700/700D system provides one baseband communication channel capable of supporting simultaneous full-duplex of SwiftBroadband functionality.
The System functions in the 1525 – 1559MHz receive band and 1626.5 – 1660.5MHz transmit band.
