Internal Heading
With the internal heading mode activated and running:
• The area showing the Position Solution Status on the
General Status screen also shows the status of the
heading process.
For example, if the Position Solution Status is “FIXED”
and the heading process has reached its operational
status, then the Position Solution status will show
successively “FIXED” and “H-FIX” (at regular intervals of
1 second).
• An additional screen, called the Heading screen, is
inserted between the General Status screen and the
Memory screens. It provides the status and results of the
heading process.
In the example below, the heading process is fully
operational (“FIXED” status), the receiver returns the
heading measurement, as well as the roll measurement
(baseline oriented perpendicular to the vehicle
centerline). There is no pitch value returned because this
angle is not measured in this case.
The table below gives the correspondence between the
heading status displayed on the General Status screen
