OEM Family

The OEM series of inertial navigation systems from Oxford Technical Solutions combine the best of GNSS positioning technology with high-grade gyros and accelerometers to deliver superior performance in a single enclosure.




Experts in GNSS and inertial technology

Advanced algorithms in the OEM systems seamlessly blend the inertial and GNSS data to provide a smooth, real-time 3D navigation solution, even when satellite signals are blocked or disturbed.


One box, turnkey solution

Combining GNSS receivers, an inertial measurement unit, internal storage and a real-time on-board processor, the OEM systems deliver a full position and attitude solution in a single compact enclosure. All systems come with an extensive software suite so your customers can post-process and plot your data at no additional cost.


Flexible, simple integration

A number of output formats including standard NMEA messages mean the OEM systems can seamlessly integrate with external sensors such as LIDAR scanners and hyperspectral cameras. OEMi+2 models take data from an external GNSS receiver and blend it with inertial data for improved performance. OEM3000 and OEM4000 models contain their own high accuracy GNSS receivers for a complete standalone solution. All of the components are ITAR free for maximum flexibility when operating in multiple countries.


Customisable to suit you

Our OEM systems have a range of optional extras that you can choose from to increase the functionality and customise the systems to suit your application. Wheel speed odometer input to further reduce drift in GNSS blackouts, and post-processing of RINEX files for 2 cm accuracy are just some of the options available. There are also dual antenna models and GLONASS compatible models to choose from.
