Our smallest INS yet with the performance you can rely on combining cutting edge MEMS IMU sensors with survey-grade GNSS receivers.



The xNAV650 is OxTS’ smallest and lightest Inertial Navigation System (INS) yet. The device makes use of the latest cutting edge technology, to deliver the precision and reliability OxTS’ customers have come to expect.

Despite combining the latest MEMS inertial sensor technology with survey-grade GNSS receivers, the xNAV650 INS is also our most competitively priced INS to date.


Tactical-grade ITAR free IMU protects against GNSS signal dropout.

Dual antenna quad constellation for accurate heading in all conditions.

Small compact size makes the xNAV650 suitable for space limited applications such as UAV Based Mapping.

The xNAV650 is OxTS’ most lightweight INS to date making it the ideal partner for Drone and UAV based applications where the longest possible flight time is sometimes required.

Despite it’s small size and weight the xNAV650 doesn’t compromise on performance.

Supported sensor integrations with Riegl, Velodyne, Z+F, Hesai, Ouster Specim, Point Grey, Phase One and other sensors.

Comprehensive OxTS NAVsuite software package included as standard, including:


Small form factor, incredible accuracy

Measuring only 77 x 63 x 24 mm the xNAV650 is our smallest INS to date. Its small form factor is ideal for any application where space is limited making it ideal for UAV-based mapping.

When weight is a factor look no further than the xNAV650 INS. Weighing just 130 g, the xNAV650 is the ideal partner when precision is crucial, but the payload needs to be as light as possible. A lighter payload and lower power consumption means longer flight times for UAVs.

As standard means that users of the xNAV650 INS can benefit from 2 cm position accuracy even in the most challenging GNSS environments.

Simple set-up, easy to use software

The xNAV650 INS benefits from optional Precision Time Protocol (PTP) time stamping functionality. All xNAV650 INS devices have the option to utilise PTP when synchronising time with LiDAR and other sensors that also utilise the feature. PTP allows for a much simpler set-up over ethernet, providing surveyors with the ability to get up and running quickly.

OxTS’ gx/ix tight-coupling technology ensures that users of OxTS inertial navigation systems receive the most accurate measurements possible even in tough GNSS conditions such as urban canyons.

OxTS Georeferencer allows users of OxTS’ inertial navigation systems to georeference pointclouds from almost any LiDAR sensor. By combining OxTS INS data with raw LiDAR data using OxTS Georeferencer, users can increase the quality of their pointclouds, decrease the time to survey, intelligently analyse data and improve project ROI.
