Dual Antenna
The dual antenna configuration dialogue is only used when Spatial FOG is being
operated with the optional dual antenna upgrade kit.
The recommended installation is with the primary antenna to the front and the
secondary antenna directly to the rear along the same axis, in which case the values
in this dialogue can be left at their factory defaults.
If it is not practical to mount the antennas in the recommended alignment, the
alternate alignment must be entered into this dialogue. It is recommended to try and
use one of the automatic ofsets where possible where the antennas must be installed
in one of four diferent automatic ofset orientations aligned on an axis.
If it is not possible to use one of the automatic ofsets, the antennas can be installed in
any configuration and a manual ofset should be entered. The manual ofset is
measured from the central base of the secondary antenna to the central base of the
primary antenna in the body co-ordinate frame (X positive forward, Z positive down). If
using a manual ofset, please be careful to measure the ofset accurately, as even
small ofset errors can result in relatively large heading errors e.g. 2 cm error = 1.15
degrees heading error with a 1 metre separation.
When using an automatic ofset, the manual ofset values are ignored and when using
a manual ofset, the automatic ofset selection is ignored.
