Quanta Extra computing unit is a printed circuit board and features a board to board connector as main interface for rapid integration and a remote IMU. The IMU is the Apogee-I remote IMU
Quanta Extra is an OEM product and is not intended to be used without being enclosed within a protective cover that will address all protection and safety requirements.

Directions of sensors axes
The inertial frame is defined as a standard right-handed North, East, Down (NED) frame (X,Y,Z) as represented in the picture.
The inertial frame is attached to the Apogee-I IMU and NOT to the printed circuit. This frame is also represented on the IMU housing, together with the cover target point of reference.
According to the “Right Hand Rule”, the rotations are positive clockwise in the axis direction as represented on the picture below.
Origin of measurements
Because the Quanta Extra IMU integrates several MEMS accelerometers, it integrates a built-in size effect compensation and as a result a ‘virtual’ reference point has been chosen to define the Origin of Measurements Point.
The origin of measurements, is the point where the inertial frame, as defined by the accelerometers triad, intersect.
The Origin of Measurement Point is represented by the red target on the drawings below.
Note
The pin numbering may not be the same as the one used by the connector manufacturer. Please refer to SBG provided pin numbering (in drawings)

Label and Hardware Code
SBG Systems manufacturing process is based on EN-9100 system with individual and full traceability of every component and operation. Each unit is identified by a unique serial number that can be used to trace all operations during the product lifetime such as manufacturing, calibration, tests and repairs.
In addition to a unique serial number, a hardware code is used to define exactly the device type, options, configuration. You can find on the side of the product a laser printed label that holds all these identification information. This label also includes a data-matrix code that encodes the device unique serial number.
