System Integrators + OEM

Knowing where an object is, how it’s orientated and if it’s moving is vital in many applications. But for most system builders creating an accurate GNSS-aided inertial navigation platform from scratch just isn’t realistic. However, spending large amounts of money on features you don’t need when sourcing one, or being treated as badly because you only require a small number of units isn’t appealing either.

OxTS products solve these problems and more. Our GNSS-aided inertial navigation sensors are already used and trusted in a wide-range of industries. Our OEM sensors share the core technologies that achieve the reliability and accuracy our customers require, but lack many of the more costly advanced features we’ve developed that simply aren’t required by system integrators. The result is a highly cost-effective GNSS-aided inertial navigation unit that’s ready to be incorporated directly into your own product. We’re also still a relatively small company, which surprises many people. Being small means we value all our customers equally, and are able to respond quickly and efficiently to meet customer requirements.

Please contact us to discuss our OEM products and how we can support you with your  integration needs.


Our OEM product line shows our commitment to providing high-precision GNSS and inertial navigation technology to OEM’s and system integrators. Our compact OEM products are ideal for integration inside any solution that requires continuous position and high-precision orientation data.



The xOEM500 inertial navigation system from OxTS is an OEM board set version of the popular xNAV500 system. Combining GNSS technology with high performance miniature inertial sensors, all embedded on a single compact board, the xOEM500 delivers a complete navigation solution to system integrators.




The xOEMcore is a combined 6-axis inertial measurement unit and navigation system with sensor fusion in one compact OEM module. In its base form the xOEMcore measures and outputs raw accelerations and angular rates with small, high-grade MEMS gyros and accelerometers. But with a simple upgrade the xOEMcore is turned into a full inertial navigation system, able to take aiding data from external sources such as GNSS and blend it in the on-board Kalman filter. It is ideal for integration inside any solution that requires robust, high-performance position and orientation.


Customers and system integrators use our products for a wide variety of applications. Here is a selection of successful ones.

Aerial surveying
High-frequency and accurate position, orientation and velocity updates make these the perfect direct georeferencing system to embed in your product.

Autonomous vehicles
Blending GNSS and inertial data means our sensors provide more robust measurements with no position black-outs in tunnels or under obstructions.

Direct georeferencing
Accurate position, velocity and orientation measurements updated at up to 250 Hz make this a great embedded georeferencing sensor.

Mobile mapping
One-centimetre accuracy, resilience to multi-path and single-satellite aiding makes OEM sensors very reliable.

Platform stabilisation
RT sensors capture the data required for modelling control systems, and can also validate the results in real-world tests.

Ethernet and RS232 output of position orientation and velocity feed your control system the information it needs to act on.

Road profiling
OEM sensors supply position and orientation information to accurately georeference other measurements.

Unmanned aerial vehicles
Feed accurate real-time position and attitude information to your device with an OEM sensor. The OEMi+2 adds inertial navigation to existing GNSS solutions.

NAVconfig default settings

Learn how to edit the default settings loaded by NAVconfig. Whether you use an OxTS system on a vehicle proving ground and always use RTCMV3 differential corrections, or are a system integrator that has a fixed orientation of the inertial navigation system, this technical note describes how to change the default OxTS settings loaded by NAVconfig to any configuration that you require.



Customising NAVconfig options

System integrators can edit which options are available for end-users in NAVconfig. The standard options loaded for an OEM sensor may not be suitable or relevant to an integrator’s application. This document describes how to add or remove options in NAVconfig, to prevent end-users changing the altitude model, for example.
