Measurements
The receiver will measure the heading angle of the vector
connecting the secondary antenna to the primary antenna.
On the receiver’s General Status screen, the receiver will
display “AUTO” or “SDGPS” indicating that the position for
the primary antenna is either computed in autonomous or
SDGPS mode respectively.
Press one of the vertical keys to see the computed position
for the primary antenna (marked ) and the heading
screen. No position is computed for the secondary antenna
(marked ).
Use the Web Server to configure the receiver:
• Go to Receiver > Position > Heading Setup
• Set Mode to Heading. This automatically sets Input to
Internal.
•Use the Length Type field to choose the way you want the
receiver to specify the baseline, i.e. the distance between
the primary and secondary antennas:
