Roll Pitch Yaw

Another output with graphical representation is Roll/Pitch/Yaw, or ‘RPY’ under ‘World frame’. It shows the Roll, Pitch and

Yaw angles around the aircraft’s principal axes (with respect to Earth’s frame) and visualizes them in two widgets seen in

Figure 13. Widget on the left (Figure 13) combines Roll & Pitch data into a single instrument, while compass on the right

shows Yaw angle, or Heading of an object. Same as before, numerical data is still visible in the right part (Figure 18, section 3)

of GUI, under ‘Aircraft Principal Axes’.

The TransducerM calculates the Yaw (heading) angle based on the magnetometer reading during its initialization process

shortly after its power on. That is, the local magnetic field during the TransducerM start up is recognized as the reference

magnetic field, and if the X-Axis of TransducerM (the sensor frame) is pointing to the north direction of this local magnetic

field, the Yaw (heading) reading is zero degree.

Save Setting

It is, however, worth mentioning that all the settings, except calibration button, selected in Figure 8 section 1, will be effective

only for current session and once the module is started up again they will be lost. To make settings permanent you can click

‘Save Settings’ button to burn them into the flash memory of TransducerM from which they can be recalled next time it starts

up.

You can use the button (as shown in Figure 15) to reset the setting to its default, and then click ‘Save

Settings’ to save the settings into the TransducerM flash memory.
