4 Introduction
Certus OEM is a next-generation miniature GNSS / NS & AHRS system that provides accurate
position, velocity, acceleration and orientation under the most demanding conditions. t combines
temperature calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with a
dual antenna RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver
accurate and reliable navigation and orientation.
Certus OEM will provide outstanding results when mounted, configured and operated correctly.
Please read through this manual carefully to ensure a successful outcome for your application.
The Certus OEM supplement is intended to be read in conjunction with the Certus Reference
Manual.
Certus is available in a number of variants. Any reference to Certus OEM can be assumed to refer
to either, with any specific exceptions noted.
•Performance: Certus, and Certus Evo base units are available with different MEMS
sensors, offering differing levels of Pitch & Roll, and Heading performance
•GNSS receiver: the standard GNSS receiver is an Advanced Navigation Aries. A Trimble
BD992 variant is also available
A Certus Development Kit is available that includes all the cables you will need to get you started
quickly. Optional antennas and accessories are also available for pruchase.
f you have any questions please contact [email protected].
Attention
Certus OEM is an electrostatic sensitive device and must be handled with care.
Precautions must be taken when operating the unit.

8 OEM Integration
8.1 OEM Mechanical Mounting
The mechanical structure of Certus OEM forms an integral part of the OEM product in order to
provide rigidity, ensure factory calibration repeatability and performance accuracy. No mechanical
pieces should be removed from the Certus OEM product.
Certus OEM is secured using four M3 screws and washers and nuts on the back side of the
mounting surface. The length of the M3 screws will be depended on the thickness of the mounting
surface.
8.2 OEM Electrical Connection
The electrical connection to the Certus OEM is through Molex and JST connectors to board
mounted connectors.

8.2.3 Electrical connectors
The following table describes the function of each connection and the type and ordering
information for connection. Certus OEM PCB Connector is the connector supplied on the Certus
OEM PCB ready for customer connection. Mating Connector for Cables is the manufacturers
mating connector and part number, plus the part number for a precrimped 15cm cable.
This information is provided to make it easier for you to design the appropriate type and length of
connections for your specific application. To make development easier, we also provide standard
~30cm pre-prepared as described in section 6.4.

8.2.5 Interoperability with Different Voltage Systems
All signals are 3.3 volt level, however inputs are tolerant to 5 volt signals from the target interface.
f you require a different voltage level to be compatible with your target system it is recommended
that you install a voltage level translator between the signals of each device.
