ESA UNCLASSIFIED – For Official Use 3
G2G DEVELOPMENTS STARTED 1
ELECTRICAL PROPULSION SUBSYSTEM INDUSTRIALIZATION AND THRUSTER OPERATIONAL CHARACTERISATION
• Prerequisite for G2G to keep launch costs of larger platforms in present launch cost envelope
• E. g. 3 sats in Soyuz ST or 1 sat in VEGA
• Transfer time of 12 months requires new launch strategy
• First contract kicked-off Dec. 2013, second one follows in Feb. 2014
ESA UNCLASSIFIED – For Official Use 4
G2G DEVELOPMENTS STARTED 2
GALILEO 2nd GENERATION SPACE SEGMENT PHASE A/B1
• Follows Galileo-1 after 2021
• Flexibility to replenish in different planes w/ one single launch
• Increasing Galileo payload capability (ISL, increased signal power levels, upgraded PRS, more robustness, etc.)
• Two parallel contracts kicked off in Dec. 2013, third one follows
ESA UNCLASSIFIED – For Official Use 5
G2G DEVELOPMENTS STARTED 3
INTER-SATELLITE LINK PRE-DEVELOPMENT
• Improved Security− Less dependence on ground segment
− Lower number of GDDN connections
− Improved command capabilities within seconds
• Improved Accuracy Performance− Smaller ODTS UERE, faster convergence
after maneuvers, improves integrity/RAIM, AUTONAV
• Additional Benefits− Sounding of atmosphere
• Activity kicked off in Dec. 2013
ESA UNCLASSIFIED – For Official Use 6
