20sea container Adverse bad weather condition
Light Mobile Platform Fair friendly weather
condition
A dedicated hard wall mobile platform is under
purchase to be available for the CALIPSO
validation in France mid 2005
2 min to put up or down the mobile platform
equipped with TReSS remote sensors
Truck loaded with Mobile Platform ready to go
Truck and driver to be provided by École
Polytechnique But rental trucks are available in
case of schedule conflict
