It aims at testing the viability of the exchange of large amount of data, through a W-band user link and either a Ka-band inter orbit link or a direct-to-ground link, and the effectiveness of resource sharing techniques to countermeasure the propagation channel behavior. The summary results of the mission analysis activities are presented along with the orbit selection process. Emphasis is also placed on the optimization of the communication window with the Artemis satellite taking into account the Sun illumination conditions.enAccelerationAntarcticaArtemis satelliteArtificial satellitesDAVID scientific satelliteEarthItalian Space AgencyKa-band direct-to-ground linkKa-band inter orbit linkLEO-based multi-experiment scientific missionLightingResource managementSoftware toolsSpace missionsSunSun illumination conditionsTestingW-band user linkartificial satellitescommunication window optimizationdata communicationdata distributionmillimetre wave propagationmission analysisorbit selectionpropagation channel behavior countermeasureresource sharing techniquessatellite linkssolar panel illuminationvideo interactive distributionvisual communicationconference paper10.1109/AERO.2002.1036843http://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=103684354dcce088580fe1368eeb002
