Relative Translation

Measures the relative translational motion between two frames

Description

A relative translation sensor measures the displacement, velocity, and acceleration of frame_b with respect to frame_a. For example, the displacement vector is found by: r = rb - ra.

The sensor generates three vector outputs containing these measurements, expressed in the frame specified by the Resolved Frame parameter. Specifically, the resulting vector can be resolved into one of three frames: frame_a, frame_b, or Inertial (global frame).

TMOutputP

Real signal of dimension 3 that specifies the displacement of frame_b with respect to frame_a.  The measured quantity is expressed in the frame specified by the parameter Resolved Frame.

TMOutputV

Real signal of dimension 3 that specifies the velocity of frame_b with respect to frame_a.  The measured quantity is expressed in the frame specified by the parameter Resolved Frame.

TMOutputA

Real signal of dimension 3 that specifies the acceleration of frame_b with respect to frame_a.  The measured quantity is expressed in the frame specified by the parameter Resolved Frame.
