Ellipse-N is a small-sized high performance RTK Inertial Navigation System (INS) with integrated GNSS receiver. It provides Roll, Pitch, Heading, Heave, and Navigation data.
This light-weight sensor includes a MEMS-based Inertial Measurement Unit (IMU) integrating three gyroscopes, three accelerometers, and three magnetometers. It embeds a dual-frequency RTK, Quad constellation GNSS receiver. Ellipse-N runs an enhanced Extended Kalman Filter (EKF) which fuses inertial data with GNSS, Odometer, and RTK corrections for excellent orientation and navigation data in the most challenging environments.

Perfectly Suited to Marine Applications
For such a compact and cost-effective sensor, Ellipse-N features an advanced heave capability which automatically adjusts to the wave period. Ellipse-N is water-resistant (IP68) and is perfectly suited to marine applications such as Unmanned Marine Vehicle (UMV) orientation and navigation, Buoy or Racing Boat Motion Monitoring, etc.
