Reference Frames Within SPAN

The reference frames that are most frequently used throughout this manual are the following:

•the Local-Level Frame

•the SPAN Body Frame

•the Enclosure Frame

•the Vehicle Frame

5.1The Local-Level Frame (ENU)

The definition of the local level coordinate frame is as follows:

•z-axis – pointing up (aligned with gravity)

•y-axis – pointing north

•x-axis – pointing east

Figure 9: Local-Level Frame (ENU)

5.2The SPAN Body Frame

The definition of the SPAN body frame is as follows:

•z-axis – pointing up (aligned with gravity)

•y-axis – defined by how the IMU is mounted

•x-axis – defined by how the IMU is mounted

To determine your SPAN x-axis and y-axis, see Table 7, Full Mapping Definitions on page 43. This frame is also known as the computation frame and is the frame where all the mechanization equations are computed.
