The Ellipse-N is a compact, high-performance single-antenna GNSS-aided inertial navigation system engineered for precision orientation, positioning, and heave in marine environments. Integrating a dual-band, quad-constellation GNSS receiver with a cutting-edge MEMS IMU, the Ellipse-N uses advanced sensor fusion algorithms to maintain robust navigation even in challenging conditions such as GNSS outages or dynamic motion. Its compact design, low noise gyroscopes, and resistance to vibrations make it an ideal solution for USVs, AUVs, instrumented buoys, and other marine systems demanding precise real-time navigation.
The Ellipse-N supports inputs from external sensors like DVL, odometers, and air data systems, enhancing performance in GNSS-challenged areas. Real-Time Kinematic (RTK) and post-processing capabilities using Qinertia software deliver centimeter-level positioning, ensuring adaptability across diverse marine missions. With user-friendly configuration and a versatile 18-profile motion model covering air, land, and marine domains, the Ellipse-N sets a new benchmark for resilient, high-accuracy navigation.
