11.5.11 Dual Antenna Configuration Packet
By default the system uses automatic offset with primary front and secondary rear.
When using an automatic offset:
l
There are four available configurations, listed in the Automatic Offset Orientations table below.
l
Manual offset values will be ignored and should be set to zero.
l
The manual offset values will be populated with the automatically calculated offset values.
If your antenna configuration does not match one of the four available automatic offset configurations you must
use a manual offset. These values are measured from the secondary antenna to the primary antenna in the
body co-ordinate frame.
