PROJECT BACKGROUND
In the frame of Living Planet program, ESA is developing the FLEX (FLuorescence EXplorer) Earth observation satellite, which will provide vegetation fluorescence data to increase our understanding of actual photosynthetic efficiency.
LEONARDO is in charge of the high-resolution FluORescence Imaging Spectrometer (FLORIS), which will study vegetation fluorescence.
CUSTOMER REQUEST
The system has to position in 6 degrees of freedom the optical component in front of the vacuum chamber (TVC), in which the instrument is installed.
The necessary travel in Z (vertical motion) for this application is relatively high (± 175 mm).
THE SOLUTION
To realize this OGSE (Optical Ground Support Equipment), SYMETRIE integrates a BREVA hexapod which meets the high-performance requirements associated with a Z translation table in order to increase the vertical travel range of the system while benefiting from the hexapod 6 degrees of freedom.
This solution allows making the requested travel range while optimizing the overall dimension and limiting development time.
The hexapod and the table can be disassembled to be used separately, which gives even more flexibility for further uses.
For this solution as for any Symetrie product, electronics and software are integrated.
