SPAN Tab

The SPAN Tab is used to view the current status and configure the IMU used, the rotation and translation for a primary antenna as well as a secondary (if required) and set an alignment mode.

SPAN Status Window

Use the SPAN Status Window to view the current status including position, velocity and attitude of the IMU.

SPAN Configuration Window

SPAN technology combines GNSS and INS into one system to offer a solution that is more accurate and reliable than either GNSS or INS can provide alone. Refer to OEM7 SPAN Overview for a SPAN overview and details regarding SPAN configuration.

IMU

Use the drop menus to select the IMU and the Port it will use. If using the PwrPak7-E1, do not change the default IMU type.

INS Rotation

Use this section to enter the rotational offset from the IMU body frame to the vehicle frame (RBV). Refer to SETINSROTATION command for explanations of other Rotational Offset Types available using the command line.

INS Translation

Use this section to enter the translational offset (or lever arm) from the IMU center of navigation to the phase center of the primary GNSS antenna, as measured in the IMU frame.

Check the Antenna 2 checkbox to enter an offset to a secondary GNSS antenna. This information is only required when using SPAN with Dual Antenna. Refer to the SETINSTRANSLATION command for explanations of other Translation Offset Types available using the command line.

Alignment Mode

Set the Alignment Mode to define the method used to initialize the SPAN system.

Refer to the ALIGNMENTMODE command for the mode definitions.

Once settings selected, press the APPLY button to save the changes or the CANCEL button to return to previous settings.
