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. Accuracy : 0.05° Roll and Pitch over 360° (RTK) 0.2° Heading (RTK with high dynamics) 5 cm Real-time Heave, adjusted to the wave period 1 cm GNSS Position Key Features: Very Low Noise Gyroscopes 64-bit architecture for high end filtering processing GPS / GLONASS / BEIDOU / GALILEO receiver Differential Corrections Post-processing Connection to Odometer 200 Hz Output Rate Accuracy and features are available in the IP68 box enclosure, or in the PCB-mounted 17-gram OEM version. 2 years warranty 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.
