Magnetic Calibration; Using The Spatial Manager Software; Using The Packet Protocol - Advanced Navigation Spatial OEM Reference Manual

2D calibration involves three level rotations about the Z axis and is designed for vehicles that
cannot easily or safely be turned upside down, such as full size cars, planes and boats. 3D
calibration involves rotating through all orientations and is designed for vehicles that can easily and
safely be rotated upside down, such as model size vehicles. 3D calibration offers slightly better
performance and is recommended where possible.
Please note that if Spatial is going to be used in a vehicle, the calibration should be performed
while Spatial is mounted in and fixed to that vehicle. This means that the whole vehicle must be
moved to perform the calibration. The calibration needs to be performed in an area away from
sources of magnetic interference. For example if Spatial is installed in a car, the calibration should
not involve driving over steel drains or reinforced concrete etc. If Spatial is being calibrated to
operate standalone, the calibration should not be done on a desk with a steel frame.
7.6.1 2D Magnetic Calibration
The following procedure should be used to perform a 2D magnetic calibration.
7.6.1.1

Using the Spatial Manager Software

1. The unit should be powered in a level orientation and kept stationary.
2. After power on wait 5 minutes for the temperature and filter to stabilise.
3. Open Spatial Manager and connect to the device. Ensure that the device has a GNSS fix
before proceeding.
4. In the Tools menu, open Magnetic Calibration. Click the 2D Calibration button.
5. Whilst keeping as level as possible, rotate the unit in either direction through three full
rotations.
6. Check the status in the Magnetic Calibration window to ensure that the calibration
completed successfully. If not successful click Cancel, wait 2 minutes and repeat from step
4.
7.6.1.2

Using the Packet Protocol

1. The unit should be powered in a level orientation and kept stationary.
2. After power on wait 5 minutes for the temperature and filter to stabilise.
3. Ensure that the device has a GNSS fix before proceeding
4. Send the Magnetic Calibration Configuration Packet with the action Start 2D Magnetic
Calibration.
5. Whilst keeping as level as possible, rotate the unit in either direction through three full
rotations.
6. Read the Magnetic Calibration Status Packet to ensure that the calibration completed
successfully. If not successful, send the Magnetic Calibration Configuration Packet with the
action Cancel, wait 2 minutes and repeat from step 4.
7.6.2 3D Magnetic Calibration
The following procedure should be used to perform a 3D magnetic calibration.
