The xNAV500 is a compact, lightweight GPS-aided inertial navigation system, perfectly suited for all applications where size and weight as well as performance matter. It measures and outputs position (50 cm), heading (0.15°), roll/pitch (0.05°) and much more in real-time. Your data can also be post-processed later with our advanced software suite, included free of charge. It is ideal for use on UAVs and other weight constrained applications.
