Precautions
The xOEM contains delicate, exposed electronic circuits and components that can be damaged by
electrostatic discharge (ESD). When handling, care must be taken so that the device is not damaged.
Damage due to inappropriate handling is not covered by the warranty.
Prior to installation it is recommended to carefully read this manual and ensure the following
precautions are taken:
▪
Do not open the protective packaging until you have read the following and are at an approved
anti-static workstation.
▪
It is best to wear an ESD wrist strap when handling electronic components. If you do not have
an ESD wrist strap, keep your hands dry and first touch a metal object to eliminate static
electricity.
▪
When handling the system, avoid touching any metal leads or connectors.
▪
If working on a prototyping board, use a soldering iron or station that is marked as ESD-safe.
▪
Always discharge yourself by touching a grounded bare metal surface or approved anti-static
mat before picking up an ESD-sensitive electronic component.
▪
Use an approved anti-static mat to cover your work surface.
Compliance testing
OxTS has not carried out any regulatory compliance testing for this product as it is solely intended for
system integration and development purposes. This product should not be used in an end user
application without undergoing regulatory compliance testing as part of another complete product.
The xNAV systems; the enclosed versions of the xOEM systems, have passed regulatory compliance
testing so there is no reason to believe that the xOEM would affect the outcome of testing when
properly integrated into an end product.
Any use or misuse of the xOEM in a manner not intended may impair the protection provided. OxTS
is not liable for any damages caused by the misuse of the equipment
Hardware description
Overview
The xOEM is a miniature GNSS-aided inertial navigation system. It combines dual GNSS receivers
with a tactical-grade IMU to provide a compact navigation solution. Built as a board-set configuration,
the system also includes 32 GB data storage and an on-board processor running the real-time
strapdown navigator and Kalman Filter.
The dual receiver integration allows greater heading accuracy with wider antenna baselines and
ensures stable heading performance even when stationary and during low dynamics. The custom
built 6-axis IMU consists of high-grade MEMS gyros and accelerometers. The sensor fusion between
the GNSS receivers and inertial sensors is done seamlessly in real-time for a continuous 100 Hz
navigation output. Data is automatically logged to the 32 GB eMMC for added data protection and
redundancy.
