sensing reference frame (SRF)


physical reference frame in which individual gyro axes outputs are provided


  • NOTE 1 In case of a single-axis configuration, the sensing axis is the Z-axis of the SRF.
  • NOTE 2 The sensing axis alignment w.r.t. the reference frame (either MRF or ARF) is defined either by the unitary vector of the ZSRF expressed in the reference frame or by the transfer matrix between the SRF and the reference frame.
  • NOTE 3 The sensing axis misalignments are the angular projections of the true Z sensing axis on the X_SRF and Y_SRF. Misalignment errors are expressed as half-cone errors, i.e. root-sum square of both projections.
