xNAV250 GNSS-Aided INS

The xNAV250 is part of the OxTS xNAV v3 series of inertial navigation products that combine GNSS technology with high-performance miniature inertial sensors for high performance,  lightweight INS, especially for drones and UAVs. The xNAV v3 series models include the xNAV550, the xNAV500, the xNAV250, and the xNAV200.

The OxTS  xNAV250 GNSS-aided INS is ideal for users requiring maximum performance on a tight budget. The xNAV250 uses the same survey-grade dual-frequency GNSS receivers and custom MEMS IMU as the xNAV550, for centimeter-level position accuracy, precise orientation and true heading. The only difference is the xNAV250 is a logging only solution, allowing users to download data from the system and post-process it with the OxTS advanced post-processing software, which is included free of charge.
