• Mission Objectives
• Dual primary mission objectives
• Over land, measurement of the soil moisture
  contents in the upper soil layer
• Over ocean, measurement of sea surface salinity
• Secondary mission objective
• Cryosphere
• Mission objectives are accomplished by measuring
  the L-band emissivity at dual
• polarizations and multiple angles from 755.5 km
  polar orbit at 6 a.m. local time

• System / Configuration
• Recurrent PROTEUS satellite bus, provided by CNES
  (contribution in kind)
• Payload developed by ESA, based upon the MIRAS
  instrument development performed under
  TRP/GSTP/EOPP
• Recurrent Flight Operations Center from PROTEUS
• Payload Data Segment, development funded
  nationally by Spain
• System Engineering and Satellite AIT by Alcatel
  (PROTEUS-Prime), to be funded jointly by CNES and
  ESA

  2003
• Ground Segment Phase A just kicked-off.
• Future Planning
• Full Programme proposal to PB-EO for approval
  mid-2003
• Payload phase C/D to commence December 2003
• Satellite Engineering Support to be phased
  accordingly
• Ground Segment phases B/C/D early-2004

• Industrial configuration
• Two major contracts
• Payload Development with CASA EADS as Prime
  Contractor
• industrial consortium mainly driven by the
  heritage from the MIRAS development activities
• MIER, Astrium, HUT/YLINEN, Contraves
• Subsystems so far unassigned MGSE, Harness,
  Thermal control H/W
• Some re-industrialization of subsystems with
  development heritage might be
• possible, but is restricted by approx 18 M
  additional Spanish funding through
• GSTP3.
• System Engineering and Satellite AIT with Alcatel
  as developer of the
• PROTEUS bus.
