EUTELSAT: POWERING THE FUTURE THROUGH INNOVATION Yohann Leroy, Chief Technical Officer, Eutelsat

INNOVATION - PART OF EUTELSAT’S DNA

Innovation is a key element for success in a very competitive telecommunication market Eutelsat has always been at the forefront of satellite innovation 1984: First transmission in DVB-S standard

1996: Development of DiSEqC standard

2000: First satellite with electrical propulsion (E16C)

2000 & 2002: Maiden flights of Atlas 3, Atlas V, Delta IV

2002: First satellite with on-board multiplexing

2003: First HD demo channel

2004: First satellite with Lithium-Ion batteries

2010: Highest capacity satellite ever launched (KA-SAT)

2013: First UHD demo channel

Innovation - all about finding the right balance between creativity and rigor Open innovation Continuous effort in collaboration with customers and

other external partners: research institutes, work shops, etc.

Evolution of the offer in our core market but also objective to address new or emerging markets (e.g. Internet of Things)

Invest into highly innovative projects and companies

Looking beyond the satellite itself Satellite is part of a system including ground segment

Innovation can be at satellite level, but it can also be on

the ground, in products and services or in the interaction between the satellite and the ground equipment

INNOVATION - PART OF EUTELSAT’S DNA

ELECTRIC PROPULSION IS A GAME CHANGER, THANKS TO THE MASS SAVINGS IT INDUCES

More than 50% of the mass of a chemical propulsion satellite is made of propellant Electric propulsion is much more efficient than chemical propulsion The thrust per kilogram of propellant is much

higher with electric than with chemical propulsion

This can be used in two ways Either to reduce the mass of the satellite Or to increase the number of payload

equipment on-board… … or a mix of both

9

ELECTRIC PROPULSION IS A WELL PROVEN TECHNOLOGY BUT WAS NOT USED SO FAR FOR ORBIT RAISING

Electric propulsion is well-proven technology Eutelsat is for example operating satellites using

electric propulsion for station-keeping since 2000

Electric propulsion was so far not used by commercial satellite operators for orbit raising Electric propulsion is more efficient, but less

powerful than chemical propulsion As a result, reaching the geo orbit takes longer in

electric than in chemical propulsion… and time is money!

SESAT 1

KA-SAT

Electric propulsion satellites can be launched with Ariane 5 in the lower position, but this was the only cost-effective solution With the arrival of the Falcon 9 rocket from SpaceX, satellite operators now have two options Savings in launch costs compensate delayed OSD, and mass savings gives some room of manoeuver to enhance the satellite performance (higher power to improve the bit/s/Hz ratio, more flexibility,…)

SPACEX HAS CHANGED THE RULE OF THE GAME

Ariane V

Falcon 9

KA-SAT, launched in 2010 over Europe was the highest capacity commercial satellite ever built Ka-band HTS Capacity over Latin America will be put into service in first half 2016 with EUTELSAT 65 West A Ka-band is the band of choice for consumer broadband HTS. For other verticals, it all depends on the trade-off between availability and cost of bandwidth

Throughput Satellite

Capacity of a satellite is limited by the amount of spectrum it can operate

With traditional wide-beam satellites, each frequency can be used only once

If coverages are tighter, then the same frequency can be used over separate zones, without creating interferences

LEO CONSTELLATIONS - A COMPLEMENT TO GEO HTS SYSTEMS

LEO constellations is something Eutelsat is currently looking at The main benefit of LEO orbit is that it reduces the latency compared to GEO

Cost of an LEO satellite part of a constellation is expected to be much lower than GEO Standardized design and manufacturing in

series Satellite failures in a large constellation can

be more easily accommodated But GEO satellites design and manufacturing

process are expected to benefit as well from industrial progress brought by LEO

15

LEO CONSTELLATIONS – NOTICEABLE ADVANTAGES

But: Most Internet applications, in particular the

most bandwidth-hungry ones, are not latency sensitive

Unlike GEO, LEO satellites are not fixed. Three negative consequences: LEO satellites fly most of the time above regions

where there is nobody to serve. Tracking antennas are needed. To serve a given region, you need a lot of LEO

satellites up and running from day 1

Specific space debris mitigation plans will also need to be set up as in LEO, the risk of collision is much higher than in GEO, and with a large constellation, this risk increases exponentially and chain reaction could occur

Eutelsat satellite are designed such that they incorporate flexibility features: ability to change orbital location, coverages, frequency plan We need flexibility to adapt to market uncertainties, and market evolution over the 15 years of a typical satellite lifetime Flexibility can be dealt with at satellite level, but also at fleet level. This is much easier for satellite operators with a large fleet of satellites We believe flexibility at satellite and fleet level has value for the customer as well

FLEXIBILITY: IMPORTANT FOR US… AND FOR OUR CUSTOMERS

EUTELSAT QUANTUM: BRIEF OVERVIEW

Courtesy Airbus Defence & Space

Today, classical satellites are defined by static definitions: its coverage (pattern generated mechanically) its amplification chains (« transponders »)one amplifier per chain its frequency plan (depends on ITU region and applications: TV, internet, governmental,

news gathering, etc.)

These are optimized to best meet market requirements and evolution forecast. Has worked very well and will continue to do so, but: Applications need to adapt to the satellite resources in orbit Higher flexibility is key in fleet management (relocation of satellites along the

geostationary arc, for regional regulation, to match to applications, etc.) Extra complexity and flexibility has typically meant increased cost

EUTELSAT QUANTUM – WHY?
