Small Space Systemsto enhance the defence space assetsSmall Space Systems integrated and interoperable withcurrent Space Assets of Defense (COSMO, SICRAL), toenhance their capabilities:•Improve responsiveness and effectiveness for specific crisisscenario•Additional sensors (optical, passive, sounders…) and telecomservices•Complement COSMO observations, using same ground networkand having data fusion in processing•LEO Telecom services may use SICRAL 1B as GEO (visible atleast for 10min in most orbits)•A real breakthrough may result from deployment of low costformations, for Imaging, ELINT, Telecom and other operationalapplications (e.g. meteorology)13All rights reserved © 2007, Thales Alenia Space

Possible Launch ScenariosSeveral launch Options are possible for the proposed Micro-Satellites of which thetwo dominant low cost are:• Expendable Launch Vehicle (ELV) Delta 4, Atlas v, Delta 2, Zenit 2 , Soyuz, Taurus PSLV, Falcon.• Converted Missiles Minotaur 1, Cosmos 3M, Dnepr 1, Start, Rockot, Minotaur 4.In addiction Micro Satellites meet Avio Launch requirements: E.g.

EO Mission – SAR Satellites Constellation17LEO Sun Synchronous Orbit grants globalEarth access capabilities (including polarregions).LEO inclined allow to improve the revisit timeperformance on the mid latitude andequatorial areas but do not allow globalEarth accessSAR Payload grants night/daylight and allweather observation capabilities.Access areas can be both right and leftlooking within a typical incidence angle rangefrom 20° to 60°The revisit time depends on the selectedorbital design and on the number ofdeployed satellitesOn the whole Mediterranean areas aconstellation of 12 SAR satellites operatingat about 300km altitude is able to provide anaverage revisit time ranging from 2 hours(inclined solution) to 3 hours (SSO solution).LEO InclinedLEO SSOAll rights reserved © 2007, Thales Alenia Space

EO Mission – Optical Satellites ConstellationLEO InclinedLEO SSOOptical Payload requires daylight and cloudfree observation conditions.Access area is nadir looking with a typicalFOV of +/-50°The revisit time depends on the selectedorbital design and on the number ofdeployed satellites.On the whole Mediterranean areas aconstellation of 12 Optical satellitesoperating at about 300km altitude is able toprovide an average revisit time ranging from3.5 hours (inclined solution) to 4.5 hours(SSO solution).Solar illumination condition (e.g. reduced inWinter season on the northern hemisphere)and cloud coverage distribution can degradethese performance.18All rights reserved © 2007, Thales Alenia Space
