Oxford Technical Solutions (OxTS) offers a future-proof inertial navigation system (INS) board set for system integrators.
The xOEM v3 includes the architecture from the company’s IP65-encased xNAV v3 as well as a full range of software interfaces, providing integrators maximum configuration flexibility, real-time monitoring, post-processing and analysis. Software interfaces can be customized using the OxTS NAVsuite. Plugins can be created using the company’s NAVsdk, allowing the xOEM v3’s software to be easily packaged and included as part of a product.
The board set is compact at 150 grams, which enables manufacturers to seamlessly integrate and build a high-performance INS into their products, such as commercial mapping applications on land and in the air. Its light weight means more payload capacity for other critical components. An add-on lidar georeferencing software package is also available with a sophisticated boresight calibration tool.
The high-grade MEMS inertial sensors and real-time kinematic (RTK) capable GNSS receiver within the xOEM v3 board set deliver high performance capabilities. The board set provides 0.1° heading accuracy, 0.05° pitch/roll accuracy and 2 cm global position accuracy.
