Status Of Iridium Block I Constellation


Iridium Current Constellation Longevity

Iridium uses sophisticated statistical models to forecast the

d lif i f h expected lifetime of the constellation, accounting for:

Current state of health of all Iridium satellites (down to Due-Diligence Vetted Iridium satellites (down to component level)

Future expected random component failures

gLongevity Models

Show Constellation is Predicted to Remain Viable and Supportco po e t a lu es

Future expected long term wear-out effects on critical spacecraft mechanisms and batteries

Viable and Support Transition to Iridium NEXT

Critical component models have been validated by original component suppliers

7

Block 1 Constellation Outlook is Good• Currently have 66 operational satellites and 7 on-orbit spares routinely

providing greater than 98% call establishment rate1

• Block 1 longevity outlook is favorable due to unique operational factorsg y q p• Lower than anticipated subscriber load and smart power management have

preserved battery life

• Systems redundancy, robustness and design permits graceful degradation

• Satellite processing architecture allows continuous modifications to flight software to circumvent anomalies and provide periodic performance upgrades

• Orbital altitude regime (780km) experiences 1/10th the radiation experienced by some other LEO constellationsexperienced by some other LEO constellations

• On-orbit spares provide capability to quickly replace failed satellites• At least one spare in each plane

D di hi h l i ff t d it i ibl l f il d t llit • Depending on which plane is affected, it is possible replace a failed satellite in as little as 30 days

• Our analysis indicates we’ll have a full complement of mission satellites at NEXT transition

Iridium NEXT: The Future is Everywhere


NEXT Constellation

• Upgrades & replaces current satellite fleet• Prime contract awarded Q2 2010• Anticipated to begin launching in 2015• Anticipated to begin launching in 2015• 66 satellite LEO constellation

• 81 satellites ordered: including 6 on-orbit spares and 9 ground spares

• Compatibilit ith c rrent fleet eases net ork transition• Compatibility with current fleet eases network transition

• NEXT advantages:• Maintains Iridium’s unique global coverage

M i t i I idi ’ i i l d l “ h hit t ”• Maintains Iridium’s unique in-plane and cross plane “mesh architecture”

• Expands capacity

• Higher data speeds

• Capable of supporting future product enhancements

• More cost effective to maintain and operate

• Designed to host secondary payloads


Iridium NEXT Prime Selection

12

• Thales Alenia Space (TAS) to develop and manufacture the Iridium NEXT spacecraft to replace the current satellite fleet

• TAS offers the best comprehensive solution for Iridium in terms of design, functionality, price, schedule and financing

• Fully compatible with current constellation to i lif t k t iti d t k ti it simplify network transition and network continuity

to existing customers

NEXT is Fully FundedNEXT is Fully Funded• On 28 October, Iridium announced that we have closed the financing facility for our next generation

satellite constellation

• The facility is provided by a syndicate of nine banks providing up to $1.8 billion of financing to Iridium y p y y p g p gfor the design and manufacture of Iridium NEXT


Transition from Current Constellation to Iridium NEXT• All Iridium segments (space/system control ground subscriber) will evolve incrementally

13

All Iridium segments (space/system control, ground, subscriber) will evolve incrementally and seamlessly from current constellation to Iridium NEXT

• Space segment will operate transparently throughout the transition period

• Iridium NEXT satellite vehicles (SVs) will be compatible and interoperable with current constellation ( ) p pSVs

• As Iridium NEXT SVs are launched, they will take the place of the current constellation SVs on a satellite-for-satellite basis

• System control segment will be capable of commanding and controlling both current constellation System control segment will be capable of commanding and controlling both current constellation and Iridium NEXT SVs; constellation will be operated as a single entity regardless of Iridium NEXT vs. current constellation SV makeup

• Ground segment (gateways, TT&C sites) incremental migration towards a new Teleport Network (TPN) architecture is already underwayNetwork (TPN) architecture is already underway

• For Iridium NEXT, functional distinction between gateways and TT&C functionality will become blurred – subscriber traffic can be grounded to any TPN site, and commanding of the constellation can be performed from any site

• Existing subscriber segment (handsets, data devices, services, etc.) will be compatible with Iridium NEXT satellites

• New subscriber devices will be developed to take advantage of new and unique Iridium NEXT system capabilities


Iridium NEXT is Enabled by Moore’s Law – in Space

Iridium NEXT satellites will provide much superior processing power compared to the current constellation

~9x > computational throughput

~125x > memory capacity

Many new service offerings can be provided by Iridium NEXT due to the greatly enhanced satellite processing capabilitiesprocessing capabilities
