SPAN-IGM Dual Antenna

Chapter 4

4.2.3Unaided Alignment

The unaided alignment sets the SPAN system to use only single antenna alignment options (kinematic or manual alignment).

To use this alignment mode, the configuration command ALIGNMENTMODE must be sent to the receiver.

ALIGNMENTMODE UNAIDED

4.2.4Automatic Alignment Mode - Automatic Alignment (default)

Automatic Alignment Mode Selection is the default setting for a SPAN-IGM. This mode is designed to allow alignment of the system as quickly as possible, using either an aided transfer alignment (Alignment on a Moving Vessel - Aided Transfer Alignment on page 40), a kinematic alignment (Kinematic Alignment on page 31) or a manual alignment (Manual Alignment on page 31).

The first available technique will be used, regardless of its relative quality. If you wish to guarantee a specific technique is used, or use an aided static alignment, you must select the desired alignment mode manually. No additional configuration is required to use this alignment routine.

4.3SPAN ALIGN Attitude Updates

The INS heading updates are used to help constrain the azimuth drift of the INS solution whenever possible. This is of the greatest value in environments with low dynamics where the attitude error is less observable. Slow moving marine or train applications are good examples of the intended use. By providing an external heading source, the solution drift can be constrained in these environments.

You can monitor the heading update status as outlined in the INSUPDATE log (see the SPAN on OEM6 Firmware Reference Manual (OM-20000144)).
