What is GA?- GA Definitions are ambiguous: The British Business and General Aviation Association:
• All aeroplane and helicopter flying except that performed by the major airlines and the Armed Services
UK General Aviation Awareness Council (GAAC):• All Civil Aviation operations other than scheduled air services and non-scheduled air
transport operations for remuneration or hire Aircraft Owners and Pilots Association (AOPA) – Germany:
• General Aviation is all civilian flying except for Scheduled Passenger and Cargo Airlines (OR: It´s Individual Air Traffic, just like driving a vehicle on the streets for most different nonscheduled purposes)

More than just new radio is needed for GA (HMI, data processing…)

The Need for New Satcom
• Improved data connectivity to critical aircraft domainsAircraft Control Domain (ACD)Control the aircraft• Cockpit displays• Flight Controls• FMS• Propulsion• etc
Airline Information Services Domain (AISD)Operate the airline• Airlines communication• Maintenance• EFB (Electronic Flight Bag)• Passenger support services• Administrative services
Passenger Information and Entertainment Services (PIESD)• Movies, games etc.
Passenger Owned Devices• Laptops• Cell phones • etc
Entertain the passengers
Current satcom radios• Inmarsat, Iridium• DAL‐D avionics only• Complex protocol stack
“Broadband” data for passengers• Hundreds of kbps (Inmarsat SBB)• Emails, internet connectivity…• Phone calls• Noncritical comm. in GA (Iridium)Narrowband “cockpit” comm.
• Units of kbps• High latency (tens of seconds)• Only oceanic airspaceFuture Iris radio
• DAL‐C avionics• Simple stack• Segregated comm. High performance “cockpit” comm.
• Tens of kbps (user data)• Low latency, high availability• Optimized for “sporadic data traffic”• Suitable also for continental airspace
This is what is missing and what Iris intends to deliver

Cockpit Satcom Performance Roadmap
• Performance specifications for future satcom being currently proposed under NEXUS Working Group.- Subgroup of EUROCONTROL’s NexSAT group - Objective is to update the AMS(R)S ICAO SARPS
• Following classification is proposed and used within NEXUS- Class A satcom system shall allow to: Support all the future oceanic and continental applications with low latency and high
availability (full 4D) Expected to be used in multi-link environment with terrestrial system(s) for improved reliability
- Class B satcom system should allow to: Support current and emerging ATM concepts (initial 4D) Offer additional capacity in oceanic and continental areas Extend the geographical coverage of the terrestrial infrastructure
Class C Class B Class A
Today“Current satcom”
Mid-Term Future (2017?)
Long-Term Future (2020+)This is what ANTARES intends to solve
ANTARES targets most advanced ATM applications in 2020+

UT Key Design Drivers
• Affordable for all IFR aircraft- Equipage cost should be comparable to nowadays IFR equipage For small GA needs to be in the order of several thousands of EUR
- For aircraft already equipped with datalink and satcom systems, the impact on existing avionics need to be minimized Ideally just SW upgrades of existing equipment and as little HW
modifications as possible- Communication Standard designed to allow low cost avionics Low gain antenna, single carrier transmission, no forced air cooling…
- For non-equipped aircraft (small GA) we need extremely simplified, small and cheap solution Limited features, services, simple HMI…
- Public funding reduces avionic supplier investments non-recurring cost element reduced
- The core technology (waveform, core HW elements…) should be developed once and reused across more products
10 Copyright © 2013 Honeywell
UT Key Design Drivers
• Coexistence with existing and future COM radios- Integration with future Inmarsat satcom avionics desirable- For future aircraft possible integration with other COM radios Substantial modification of aircraft radios and COM architecture Addressed in SESAR 9.44
- Via coordination with SESAR 9.44 and possibly other projects Iris waveform is expected to become part of future flexible radio products
• Mixed Development Assurance Levels (DAL)- Objective is to minimize amount of SW and HW which needs to
be designed above DAL D The need for DAL-C datalink radios is yet to be confirmed, but obviously it
doesn’t make sense to have e.g. ATN/OSI specific parts of the ANTARES protocol stack at DAL-C when ATN/OSI itself is only DAL-D.
- Avoid or absolutely minimize need for recertification of already existing SW and HW
11 Copyright © 2013 Honeywell
UT Key Design Drivers
• Technically suitable for all IFR aircraft- Different limitations for different aircraft Size, weight and form factor constraints (25x15x10cm / <4kg for small GA) Absence of forced air cooling HPA design constraints Antenna size and location constraints small low gain antenna needed Integration with existing avionics

UT Prototype – Next Steps
• Ongoing and near term activities- Consolidate the VTB and UT prototype specifications- Implement the L1 algorithms on target platform FPGA/DSP- Define the detailed L2 SW architecture- High efficiency HPA prototype development Single carrier transmission relaxes the requirements compared to
Inmarsat avionics – this needs to be exploited in order to deliver viable products suitable for small GA.
• Final objectives for phase B2- Implement ANTARES L1 and L2 on the prototype- Perform in-house testing At this stage of system development limited by absence of a
dedicated ANTARES test equipment- Support integration of the UT Prototype in the VTB and
execution of the CS testing
15 Copyright © 2013 Honeywell
Phase B2 Outcomes
• Prototype development is the major objective of this phase
• Additional objectives- Draft the “technical specifications” for the future UT product Scope comparable to MOPS – shall serve as baseline for future
standardization- Refine the supporting studies performed in previous phases Architecture analysis Electronics design analysis (primarily HPA) Interference analysisCost analysis Standardization roadmap definition
