Mounting the Pulse-20
For best measurement accuracy, a good mechanical alignment is required. During manufacturing, the Ellipse measurement frame has been carefully aligned to 0.1° with the base plate for roll, pitch and yaw angles.
In order to align properly the IMU frame with your own system, SBG Systems recommends the use of 3x alignment pins, located along two perpendicular sections of the enclosure.
Specifications
All dimensions are expressed in millimeters using the International System of Units (SI) conventions.
| Parameter | Specification |
|---|
| Size | 26.8 x 18.8 x 9.5 mm |
| Weight | 10 g |
| Material | Aluminum |
| Surface Treatment | SURTEC 650 |

The enclosure is not waterproof. Proper system sealing if the Pulse-20 has to be used in a humid environment.
Directions of sensors axes
Device coordinate frame is marked on the IMU cover a sticker. The inertial frame is defined as a standard right-handed (X,Y,Z) frame, aligned to the North, East, Down (NED) geographic frame ; 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
The Origin of Measurement Point is represented by the red target on the drawings under.

Label
SBG Systems manufacturing process is based on EN-9001 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 Pulse cover 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.
