mechanical reference frame (MRF)


ECSS-E-ST-60-20C Rev. 2


reference frame where the origin of the MRF is defined unambiguously with reference to the mounting interface plane of the sensor Optical Head


  • NOTE 1 E.g. the Z-axis of the MRF is defined to be perpendicular to the mounting interface plane. The X- and Y-axes of the MRF are defined to lie in the mounting plane such as to form an orthogonal RHS with the MRF Z-axis.
  • NOTE 2 Figure 3-5 schematically illustrates the definition of the MRF.
  • NOTE 3 For Fused Multiple Optical Head configurations, MRF should be discussed and agreed between supplier and customer.
