Figure 39: POSView Navigation Data at Sensors

Attitude Pane

Displays the angles of roll, pitch and heading of the sensor using the

sensor frame of reference. POS MV uses degrees to display the attitude

measurements and their estimated boundaries of accuracy.

Velocity Pane

Velocities of the sensor are given in the longitudinal and down directions.

POS MV uses metres per second to display the velocities and their

estimated boundaries of accuracy.
