SBB-AV-200S-LGA Cobham Aviator 200S System, Single Channel Class 4, SB-S 2.0, Low Gain Antenna

Smaller size – lower cost
AVIATOR S Series delivers ACARS services over a robust IP data link as well as multiple voice channels. It is smaller, lighter and has a lower cost of ownership than any other Inmarsat system, including lower airtime costs.

The system’s compact design is suitable for all single-aisle and wide-bodied aircraft. It is faster to install and configure, compatible
with all Inmarsat L-band antenna systems and, in the case of AVIATOR 200S, it reduces the number of LRUs down to 2, saving on space and weight, and reducing fuel burn.

The entire AVIATOR S Series product portfolio is compatible with all classes of Inmarsat SwiftBroadband services: Class 4 (AVIATOR 200S), Class 6 (AVIATOR 700S) and Class 7 (AVIATOR 600S). All our systems meet requirements for FANS 1/A operations.

Highly secure, separate domains
Built to Cobham’s uncompromising standards, AVIATOR S Series’ architecture allows for secure aircraft domain segregation with
priority for the Aircraft Control Domain (ACD) over the Aircraft Information Service Domain (AISD) and the Passenger Information & Entertainment Services domain (PIES).

Complete segregation between the three domains ensures absolute data security and meets all data communications specifications according to the standards of ARINC 781, Attachment 8.
• Ultra-compact Cobham SATCOM HELGA antenna and C-SDU two-box solution for a total system weight of less than8kg (17.6lbs) in  the AVIATOR 200S configuration
• Low power requirements consuming less than 130 watts
• Data segregation between safety and non-safety domains
• FANS 1/A compliant
• Multiple simultaneous voice calls
• Reduced LRUs to only 2 in AVIATOR 200S
• Meets all ARINC 781 specifications

System Overview

The AVIATOR 200S System is an Inmarsat aeronautical SATCOM system, which provides Inmarsat SwiftBroadband services and safety services (Class 4). It delivers secure ACARS services over a robust IP data link together with dual cockpit voice channels. The AVIATOR 200S System is a single-channel system for cockpit use and complies with ARINC Characteristic 781 Mark 3 Aviation Satellite Communication Systems. The system provides services in the L-band (1518 to 1559 MHz for the receive channel and 1626.5 to 1660.5 and 1668 to 1675 MHz for the transmit channel).

The AVIATOR 200S System provides the following classes of communication services:

• Air Traffic Service (ATS) • Airline Operational Control (AOC)

• Aeronautical Administrative Communications (AAC)

• Aeronautical Passenger Communication (APC)

The services include cockpit voice with two voice channels, IP data (Internet), ACARS over IP and Electronic Flight Bag (EFB) services for direct satellite communication in the Inmarsat BGAN Satellite Network, using the Inmarsat 4th generation satellites.

The AVIATOR 200S System consists of:

• SDU-5045 Compact Satellite Data Unit (CSDU)
• SCM-5055 Compact SDU Configuration Module (SCM)
• LGA-5005 HLD/Enhanced Low Gain Antenna (HELGA)

The CSDU is the master of the AVIATOR 200S System and controls the associated units in the system. The SCM and the antenna are powered by the CSDU.

The AVIATOR 200S System has the following features:

• Complete aircraft network segregation with priority for the Aircraft Control Domain (ACD) over the Aircraft Information Services Domain (AISD).
• ARINC 781-7 compliant network security
• Approved FANS 1/A services, including CPDLC, ADS-C and ACARS.
• Enhanced ACARS (with IPSEC VPN) and Secure Cockpit Voice.
• Media for aircraft monitoring systems and continuous positioning reporting.
• Background IP data for AISD (e.g. EFB) applications.
• ARINC 781-7 Compact 2 MCU package with active HLD/Enhanced Low Gain Antenna.
• Two cockpit voice over 4-wire connections, with three MCDU ARINC 429 interfaces for SATCOM and voice management
• Two CMU/AFIS ARINC 429 interfaces for ACARS.

Compact Satellite Data Unit (CSDU) 

The AVIATOR200S Compact Satellite Data Unit (CSDU) is a 2 MCU LRU with an ARINC600 connector. It is a highly secure system with complete aircraft network segregation for the Aircraft Control Domain (ACD) over the Aircraft Information Service Domain (AISD). The aircraft network segregation between ACD and AISD ensures highest data security and meets all data communications specifications of ARINC781-7, Attachment 8 [3] requirements. The system also meets requirements for Future Air Navigation System (FANS) 1/A operations.

SDU Configuration Module (SCM) 

The SCM contains non-volatile memory for storing the Secure Owner Requirement Table (ORT) and the User ORT, which hold the system settings. The SCM contains a writeprotected area for storing installation data (system configuration, RF cable losses, antenna system etc.) that are only updated during installation, and a user non-write-protected area for storing a phone book and the customer-specific configuration parameters. The SCM is an external module for the CSDU, making it easier to replace the CSDU while retaining all system and user settings in the SCM. If the CSDU must be replaced, the SCM remains installed in the aircraft. When the replacement CSDU is installed and connected to the SCM the system then user settings are available again. The SCM contains four Inmarsat BGAN USIM cards and one security SmartCard. In the AVIATOR 200S System system, one USIM card is used to access the Inmarsat SwiftBroadband services and the remaining three USIM cards are reserved for future use. The Security SmartCard contains integrity/ciphering keys and authentication algorithms and is used by the Aircraft ACARS Gateway (AAGW). The SCM is delivered with all five cards installed and these cannot be replaced in the field.

HLD/Enhanced Low Gain Antenna (HELGA) 

The CSDU interfaces directly to a HELGA antenna (Class 4 Enhanced Low Gain Antenna with a built-in Diplexer Low Noise Amplifier (DLNA) and High Power Amplifier (HPA). The HELGA complies with ARINC 781-7, Attachment 7 [3] ELGA (Enhanced Low Gain Antenna) mounting footprint. It uses a phased array antenna with no moving parts. Together with the CSDU it forms a Class 4 system. The LGA-5005 HELGA is compliant with ARINC 781 and has the following internal SATCOM interfaces: • 1x Coaxial RF interface (for Rx/Tx signals, power, control and BITE) to the CSDU The antenna is steered by the CSDU, which derives steering information from aircraft navigational data.
