This is the most straightforward method for determining the alignment angles

Configuring an inertial navigation product, especially as it relates to the setting of the alignment angle, is a critical step to ensure the accuracy and reliability of the system. Here are some basic steps and considerations:

Understand the alignment angle: the alignment angle is a critical parameter to ensure that the orientation of the inertial measurement unit (IMU) is aligned with the reference frame of the vehicle or application
This typically involves ensuring that the IMU's sensors are aligned with the direction and orientation of motion of the external environment.

Auto-alignment: Many modern inertial navigation products support auto-alignment, which simplifies the installation process and reduces the need for technician training. Auto-alignment can be adapted to changing requirements or environments, providing flexibility
Manual Alignment

Manual Alignment: Manual alignment may be required in certain situations, such as two-wheeled vehicle applications or when automatic alignment is not working properly. Manual alignment can provide greater accuracy, but requires more time and expertise to perform.

Two-wheeled vehicle applications: For two-wheeled vehicles, such as motorbikes or motor scooters, automatic alignment may not be applicable and therefore manual alignment must be performed. This is due to the fact that two-wheeled vehicles move with greater degrees of freedom and tilt angles, which complicates automatic alignment.

Video tutorials: In order to help users better understand the alignment angle adjustment process, companies such as u-blox provide detailed video tutorials that guide the user step-by-step through the alignment process
Video tutorials Axis alignment of the IMU: When performing manual alignment, the alignment of the IMU's axes to the vehicle's coordinate frame needs to be considered. This may involve measuring and adjusting the axis alignment angle.

Error analysis: When designing and implementing the alignment process, it is important to understand and analyse the possible sources of error, including alignment errors in the IMU itself and errors introduced during installation.

Electronic Alignment: If the IMU and mounting system cannot meet critical system objectives, alignment errors can be reduced through electronic alignment. This involves determining the alignment error term and applying a corrective alignment matrix.

Testing and validation: After the alignment process is complete, it is critical to conduct thorough testing and validation to ensure that the system is working as expected and providing the required accuracy.

Resources and support: Utilising the resources and support provided by the manufacturer, such as technical documentation, evaluation kits and customer service, can help to resolve issues that may arise during the configuration process.

By following these steps and considerations, successful configuration and integration of inertial navigation products can be ensured.
