Inmarsat Development Programme for SwiftBroadband Oceanic Safety

(Presented by Alan Schuster-Bruce, Inmarsat)

SUMMARY

At ACP WG-W (September 2011) it was agreed to include into the work programme of WG-M the validation of SwiftBroadband Safety as an additional sub-network for aeronautical safety satellite communications. The development of the necessary ICAO Manual for SwiftBroadband Safety was endorsed at ACP WG-M (May 2012). This two-part working paper provides 1) a presentation-level overview of Inmarsat’s forthcoming SwiftBroadband Oceanic Safety Service and 2) preliminary documentation of this information in a format appropriate for inclusion in the ICAO Technical Manual. In both forms, this document gives a high level description of the programme and system, a summary of service objectives and benefits and the timeline for implementation. The preliminary documentation is intended to foster discussion and group input, and is not necessarily intended to be the final form for publication.

ACTION The working group is invited to note the information on the SwiftBroadband Oceanic Safety development programme.

What is BGAN? What is SwiftBroadband?

11

BGAN is a satellite component of the Third GenerationIMT-2000/Universal Mobile Telecommunications System (3G UMTS)

• Only difference is that BGAN has a proprietary satellite radio interface.

BGAN operates over the Inmarsat I4 (4th generation) satellites.

BGAN service was introduced for ‘enterprise’ (Land portable) segment in 2005/2006 on two satellites.

Inmarsat introduced in 2007 evolutions of BGAN to offer service in other market segments: land mobile, aviation and maritime.

• These evolutions run over the same ground infrastructure as ‘Enterprise’, share the same RF carriers, are broadly the same but are optimised/tailored for the specific environment.

Service was introduced on the third I4 in 2009

SwiftBroadband is the aviation service.

Inmarsat Development Programme for SwiftBroadband Oceanic Safety

(Presented by Inmarsat)

SUMMARY

At ACP WG-W (September 2011) it was agreed to include into the work programme of WG-M the validation of SwiftBroadband Safety as an additional sub-network for aeronautical safety satellite communications. The development of the necessary ICAO Manual for SwiftBroadband Safety was endorsed at ACP WG-M (May 2012). This working paper provides an overview of Inmarsat’s forthcoming SwiftBroadband Oceanic Safety Service. It gives a high level description of the programme and system, a summary of service objectives and benefits and the timeline for implementation.

ACTION

The working group is invited to note the information on the SwiftBroadband Oceanic Safety development programme.

1. INTRODUCTION

1.1 The Inmarsat SwiftBroadband service, which operates over Inmarsat’s Broadband Global Area Network (BGAN) satellite communication network, has been in operation since October 2007, providing voice and broadband data communications to airline passengers. At present, aeronautical safety messages, such as FANS/ACARS data, are supported by Inmarsat’s Classic Aero services. This paper describes the ongoing programme of work to enhance the SwiftBroadband service to enable it to meet the ICAO performance requirements for oceanic safety services.

1.2 In addition to providing two channels of voice to the cockpit, the new SwiftBroadband Oceanic Safety services will support FANS/ACARS data. Priority and pre-emption of messages will be

utilised to ensure safety messages reach the cockpit unhindered by the commercial communications traffic load to the cabin.

1.3 A SwiftBroadband Oceanic Safety Services terminal will also be equipped to provide high bandwidth Internet Protocol (IP) data to the cockpit, enabling the future development of cockpit ATS and AOC applications. This high bandwidth data capability will be extensible to support the Aeronautical Telecommunications Network (ATN) and future concepts of operation in Air Traffic Management (ATM).

1.4 The new service also includes functionality to append aircraft position, speed and heading data to all ACARS messages transmitted to the ground over the Inmarsat satellite link, thus enabling improved location tracking of oceanic aircraft.

2. SWIFTBROADBAND SAFETY PROGRAMME OVERVIEW

2.1 SwiftBroadband Oceanic Safety Service Objectives

2.2 Airlines and Air Traffic Service Providers are keen to increase airspace capacity and operational and fuel efficiency, whilst maintaining and enhancing safety. To achieve these objectives, there are moves at international level to allow reduced minimum aircraft separations in oceanic and remote areas, in regions of controlled airspace where the satcom performance is proved to be sufficiently available and reliable. The intention is to move from the current typical minimum in-trail separations of 10 minutes/80 NM (Nautical Miles), and 60 NM between tracks, to an in-trail separation of 30 NM and 30 NM between tracks: so-called “30/30” operations or equivalent time-based separations.

2.3 To achieve reduced separations between oceanic aircraft, there is a need for a greater frequency of aircraft position reporting, and to ensure higher datalink service availability. These improvements to the ground-aircraft communications link are required to permit controller intervention, at any time, in the event that an intervention is needed if an aircraft begins to stray from the track specified in its flight plan. This in turn demands an enhancement of the minimum performance level of the communications systems supporting Air Traffic Service (ATS) voice and data safety services.

2.4 The ICAO Global Operational Data Link Document (GOLD) defines the Required Communications Performance (RCP) for the service availability and message transaction times of oceanic FANS/ACARS data communications. The GOLD RCP performance criteria are specified to ensure the provision of a safe operational service for oceanic operations.

2.5 The RCP minimum requirement for the availability of an oceanic datalink communication system in support of a safety service is 99.9% over a 12-month period, (the ‘safety’ requirement). To meet the more stringent RCP requirement in support of 30/30 separations, the end-to-end service availability of the communication system must be at least 99.99% over a 12-month period, (the ‘efficiency’ requirement). This is a challenging requirement for a ‘single path’ communications system and the implication is that the satellite communications system includes appropriate redundancy, fail-over and alternate routing mechanisms to mitigate the potential temporary failure of a range of different system constituents.

2.6 Like the Inmarsat Classic Aero services, SwiftBroadband Safety will meet the safety requirement of 99.9% availability. Planned upgrades to the BGAN network should ensure this availability is met, and the SwiftBroadband service availability will meet the efficiency requirement of 99.99% availability following an initial period of in-service operation. A range of High Gain Antenna (HGA),

ACP-WGW-19/WP-01

Intermediate Gain Antenna (IGA) and Enhanced Low Gain Antenna (E-LGA) SwiftBroadband terminals are being developed by Inmarsat’s terminal manufacturer partners to provide the required aircraft functionality in support of the GOLD RCP240 oceanic safety requirement, as shown in Figure 1.

Figure 1: Product options for Meeting the RCP240 Safety and Efficiency Requirements

2.7 Class 6 High Gain Antenna (HGA) terminals are supported that have the capability to fail-over to ACARS and voice services on Classic Aero. The E-LGA terminal is an enhanced version of the Inmarsat SB200 terminal currently in operation, with increased coverage and performance, while maintaining the very small antenna profile, low equipment weight and low cost characteristics of the existing SB200. In addition to the commercial services currently provided by SwiftBroadband to the aircraft cabin, all the SwiftBroadband Oceanic Safety aircraft terminals will be able to provide the following safety services:

• FANS/ACARS data; • 2 voice channels to the cockpit; • Prioritised IP data to the cockpit; • Aircraft position reporting.

2.8 The Inmarsat avionics manufacturing partnership and airframers have expressed their support in providing the safety service capability across this product set. Terminal modifications are underway and programme plans are being agreed with manufacturers.

2.9 SwiftBroadband Oceanic Safety System Description

2.10 SwiftBroadband uses the Inmarsat I4 satellites and Inmarsat’s Broadband Global Area Network (BGAN). The SwiftBroadband Oceanic Safety high level architecture is shown in Figure 2. As discussed, a SwiftBroadband Safety terminal may operate over SwiftBroadband only, or (as envisioned for future Class 6 terminals) may include a Classic Aero modem to allow it to fall back to operation over Classic Aero in the event of temporary SwiftBroadband service unavailability, enabling the terminal to confidently perform to the 99.99% availability level required for ’30/30’ operations. Figure 2 illustrates at high level the fallback mechanism to Classic over I4, and for the time that the I3 satellites remain available, secondary fallback to Classic over I3.

Figure 2: SwiftBroadband Oceanic Safety High-Level Architecture

2.11 To enable support for safety services over SwiftBroadband, changes are being made to the BGAN ground infrastructure and to the existing aircraft terminals. These changes will permit FANS/ACARS messages to be sent at high priority over the BGAN network, and will enable the prioritisation of cockpit voice and data over other communications traffic to the aircraft e.g. communications that may be provided to the aircraft cabin.

2.12 To use SwiftBroadband Oceanic Safety services, the Satellite Data Unit (SDU) on the aircraft will be updated to incorporate an ACARS Air Gateway (shown on the right of Figure 2) and appropriate interfaces to the cockpit avionics. The ACARS and voice interfaces will be the same as they are for Classic Aero, thus minimising the required changes on the aircraft.

2.13 The system architecture will also make use of a new ACARS Ground Gateway (AGGW) (shown on the left of Figure 2) that is currently being installed at the BGAN satellite access station sites in order to route ACARS data traffic between the aircraft and Air Traffic Service Providers (ATSPs) and Airline Operational Control (AOC) centres on the ground.

2.16 Inmarsat’s SwiftBroadband Class 6 and 7 user terminals primarily address the needs of the larger air transport, business aviation and government users.

bring satellite communications to mid-sized air-transport and business aircraft and even General Aviation (GA).

2.17 To meet this demand, Inmarsat has introduced the SB200 Class 4 Enhanced Low Gain Antenna SwiftBroadband Safety product, as an evolution of the successful SB200 Class 15 terminal. In addition to supporting all the SwiftBroadband safety services, the Class 4 terminal incorporates a number of product enhancements, the main one being improved coverage down to 5o satellite elevation angle, which aligns to the coverage of the existing Inmarsat products.

2.18 End User Service Benefits

2.19 The SwiftBroadband safety product line will offer aircraft operators a full range of options, from the fully-functional Class 6 with Classic fallback through to the smaller, lighter, cheaper terminal options where one channel only is needed. The wide range of safety product options will permit more aircraft to fit for FANS/ACARS operation and make use of satcom voice.

2.20 In addition, Inmarsat believes that the end-user prices for ACARS messaging on SwiftBroadband can be delivered at rates at least one third lower than the equivalent tariffs on our Classic aero service.

2.21 ANSPs will be able to consider new concepts of operation for aircraft equipped with the SBB/Classic product targeting the RCP240 communications performance.

2.22 The inclusion of Prioritised IP connectivity to the cockpit offers the opportunity to introduce new AOC and, in future, ATS applications, and will permit higher bandwidth applications to be developed to support services including meteorological data download, aircraft performance monitoring, and Electronic Flight Bag update.

Figure 3: SwiftBroadband Oceanic Safety Benefits

2.23 It will be possible to have the SwiftBroadband Safety capability available for validation trials in a relatively short timeframe due to the fact that ground and avionics interfaces are maintained to the maximum possible extent; thus the full benefits of satcom voice, FANS/ACARS messaging and ‘always-on’ IP communications can be brought rapidly to the aviation community.

2.27 Inmarsat and its partners are currently working to build trials partnerships for the validation flight trials beginning in Q2 2013. Inmarsat and its communication service providers intend to present the plans for trials and validation into the FAA PARC and ICAO regional datalink groups.

2.28 RTCA and ICAO Standards Development

2.29 Inmarsat and its manufacturer and communication service provider partners began the process of developing Minimum Aviation System Performance Standards (MASPS) and Minimum Operational Performance (MOPS) for SwiftBroadband Safety services in January 2009, within the RTCA SC-222 working group. The ICAO GOLD RCP methodology has been used as a baseline for the standards development. While the MOPS development is still ongoing, the MASPS is now in a mature draft form and will be of significant use in the development of the appropriate WG-M ICAO Manual for SwiftBroadband Safety. Inmarsat is additionally standardizing the BGAN system within the European Telecommunications Standards Institute (ETSI).
