In order to lead the AirShield project to a successful completion it is necessary to clearly define the objectives for all essential components of the system. The essential challenges are summarized as follows:

• MUAV platform
  High load
  Long hours of operation
  Stability in bad weather situations
  
  
• Lightweight sensors
  Minimum weight
  High measurement accuracy despite the miniaturization of the measurement instruments
  
  
• Communication and operation
  High reliability of the communication system
  Small delay for the transfer of control information
  High data rate for the transfer of information in real time
  
  
• Geoinformation and Decision Support
  Clear representation of the propagation forecast
  Inclusion of geographic data
  Inclusion of weather forecasts
