The Control & Data Management Systems (CDMS) represent highly customized products capable of providing Scientific Payloads with a complete, integrated and low resources demanding platform including:

 • Experiment Computers
 • Real time data processing subunits
 • Data Acquisition subunits for a wide range of sensors (temperature, pressure,
   estensimeters, accelerometers, strain gauges, force sensors….)
 • Actuator Drivers subunits for a wide range of actuators (stepper motors, DC
   motors, brushless motors,    injection device, heaters, peltiers, …)
 • Battery subunits
 • Power conditioning and distribution subunits
 • Dedicated experiment and data management interfaces

The CDMS, available in different qualification level, can be easily customised to experimental and platform requirements thanks to their modular, open, expandible architecture
