Heading Aiding Settings
Device settings are stored in the sensor memory. Only the configuration options that are available for
the type of sensor being used are displayed in the configurations menus. The 3DM-CX5-GNSS/INS
has eight heading options.
If the setting is an external reference, the user has to provide a heading reference (for example,
see
GPS External Receiver on page 1
). If the setting is none, the estimated heading will drift when little-or-
no changes in velocity are sensed (e.g. when stationary or traveling in the same direction at a constant
velocity). If using velocity as a heading reference, the sensor (or sensor platform) has to be moving, or
there will be no heading reading. When using the combination settings, multiple heading aiding sources
may be used. For example, if an external heading source is available but a magnetometer backup
heading is desired, select the Mag & External Message option.
For all settings, moving the platform in a dynamic way will assist in capturing an accurate heading.
To enter the Heading Aiding menu, select the sensor name in the MIP Monitor software main window,
then select Settings > Device > Heading Aiding:
