Experts in GNSS and inertial technology

The xNAV systems use compact MEMS sensors in order to be as economical as possible, both in terms of price and power. But thanks to state-of-the-art calibration techniques and advanced algorithms in the xNAV, we are able to push the technology beyond its limits to deliver exceptional performance in a surprisingly small package. By seamlessly blending the inertial and GNSS data, the xNAV provides smooth, robust outputs even in poor GNSS environments.

One box solution, no hidden extras

Combining dual GNSS receivers, an inertial measurement unit, internal storage and on-board processor all in one compact box, the xNAV delivers everything you need for a complete navigation solution. All necessary cables and antennas are included, as well as our extensive software package–NAVsuite–which features powerful post-processing and graphing software.

Easy integration

Integrating the xNAV into systems like UAVs couldn’t be simpler.

Mounting brackets are supplied to ensure a rigid installation. Standard

NMEA messages, timing sync and trigger outputs as well as event input triggers mean the xNAV can be used with an array of sensors such as

LiDAR scanners, cameras, and hyperspectral sensors. OEM board set versions are available for system integrators and we offer attractive discounts on top of our already low prices for bulk purchases.

Worldwide standard

OxTS inertial navigation systems are recognised as a symbol of precision and performance around the globe. And with zero export restrictions, there’s nothing stopping you going global either.
