Sensor Cordinate System
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.
According to the “Right Hand Rule”, the rotations are positive clockwise in the axis direction as represented in the drawing below.
Origin of measurements
Because the QUANTA-Micro 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.
Mechanical Drawing
All dimensions are expressed in millimeters using the International System of Units (SI) conventions

Mounting
Mounting solutions :
The product is designed to mount directly to a printed circuit board (PCB).
There are two recommended ways in which the product can be secured to the PCB
:
- The first method uses board mounted threaded standoffs
- The second method uses
- common components

Label
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 product 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 hold all these identification information. This label also includes a data-matrix code that encodes the device unique serial number.
