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
