The CRIES project addresses PPDR aspects where satellite is the more valuable tool (communication). The CRIES project should require an important effort of standardization to gain the adhesion of all actors in PPDR The CRIES project could latter result in operational PPDR systems for the good of everybody (God willing!). Alcatel Space is seeking European partners to promote this project. Thank you for your attention...
