PHR Context

• ORFEO Cosmo SKymed (radar) PHR (optical)
  components
• PHR Dual environment Defense Civil
• Inter-operability needs
• Defense partner shall be able to acquire, process
  data from the defense partner
• Defense partners shall be able to send
  programming requests to the partner and receive
  acquisition plans
• Civilian partner shall be able to acquire,
  process data from the civilian partner
• Civilian partners shall be able to send
  production request to the civilian partner and
  receive products
• PHR developed in an european cooperation context
  
• Austria and Belgium , Sweden and Spain
• National funding in exchange for industrial
  return, images acquisition, etc
• Italie Turin agreement
• In the civilian context, needs of common access
  with other satellites like SPOT (Cf. INCAS
  demonstration with SpotImage SPOT catalog)
• In the defense contexts, needs of inter-operable
  access with other defense satellites ground
  segments

PLEIADES within ORFEO

• ORFEO status (end-2003)
• Cosmo SKymed PHR ground segments independant in
  terms of architecture and interfaces
• Design choice PHR will expose interfaces
  compatible with a future multi-sensor level in
  a single development unit, called Access Unit
  (provision for future federation with
  multi-sensor layer)

PHR Users Access Services

• Provides the users with MMI and tools to access
  the PHR services
• Browse image catalog
• Deposit programming requests (ICR)
• Deposit image production requests (ICR)
• Follow the progress of requests
