3.1.2. Device mechanical alignment
For best measurement accuracy, a good mechanical alignment is required. During manufacturing, the
Apogee measurement frame has been carefully aligned to 0.02° with the base plate for roll, pitch and yaw
angles.
To ease the yaw alignment (X axis), the base plate features two alignment holes Ø 4 mm H8 that
guarantees with two taper pins Ø 4 mm h7 a yaw alignment better than ±0.04°.
Note: The base plate is the same for the Apogee A, E, and D models.
3.1.3. Origin of measurements
The Apogee offers the possibility to output data at different measurement points.
The default center of measurement is located on top of Apogee enclosure, on the coordinate frame center
drawing. It is represented on the mechanical outlines by the symbol. This point is defined to simplify
installation.
Alternatively, user can select between two other center of measurement points:
●
Alignment hole (aligned to the bottom of the base plate)
●
Bare IMU center of measurement, represented by the symbol.
