The Ellipse-D is a precision-engineered, dual-antenna GNSS-aided inertial navigation system designed to deliver the highest orientation, positioning, and heave accuracy in a compact form factor. Equipped with a dual-band, quad-constellation GNSS receiver and an advanced MEMS IMU, it delivers robust navigation and true heading even in static or GNSS-compromised marine conditions.
Supporting RTK, DGNSS, and SBAS, Ellipse-D ensures centimeter-level positioning, while its DVL input dramatically enhances performance during GNSS outages by providing reliable dead reckoning in subsea or obstructed environments.
Designed for hydrography, USVs, marine robotics, and mobile mapping, Ellipse-D integrates jamming and spoofing detection features, delivering real-time interference flags to maintain signal integrity. Its 8 GB onboard logger enables detailed post-operation review and performance enhancement through Qinertia post-processing software, making the Ellipse-D a versatile choice for demanding marine and offshore applications requiring heading stability and high-accuracy navigation.
