Oxford Technical Solutions, a designer and manufacturer of Inertial Navigation and GPS/GNSS products, has announced the release of its new compact and lightweight GNSS-aided inertial navigation system, the xNAV550, along with an OEM board set version, the xOEM550.

The xNAV550 is the latest model in the xNAV family and the first to offer a position accuracy of 2 cm, yet remains a compact (425g) GNSS-aided inertial navigation system. Perfectly suited for all applications where size and weight as well as performance matter, it is ideal for use on UAVs and in other weight-constrained applications.

Featuring dual GNSS receivers and a state-of-the-art custom built inertial measurement unit, the xNAV550 constantly monitors position, orientation and velocity with high accuracy in real-time. 4 GB of on-board storage is available, automatically logging data for an added layer of protection. Data can be easily downloaded from the system and post-processed using advanced software included as standard at no extra cost.

Integrating the xNAV550 with cameras, laser scanners or other sensor arrays is easy thanks to the NMEA outputs, a 1PPS, and event input triggers for synchronisation and time stamping. These features, and the convenience of the one-box solution, ensure it is quick and easy to acquire accurate data required for direct georeferencing.

The xOEM550, the OEM board set version of the xNAV500, offers a lightweight solution for system integrators looking for a high performance INS to build into a complete scanning and georeferencing system, weighing in at just 165 g.
