Ellipse-E is a small-sized high performance Inertial Navigation System. It provides Roll, Pitch, Heading, and Heave, and computes Navigation data when connected to an external GNSS receiver. It accepts Odometer aiding to maintain the best accuracy in automotive environments. This light-weight sensor (49 grams) includes a MEMS-based Inertial Measurement Unit (IMU) and runs an enhanced Extended Kalman Filter (EKF) which fuses inertial and aiding information to provide accurate real time orientation and navigation data. High Accuracy for Such a Small Sensor: up to 0.05° Roll and Pitch over 360° (RTK) up to 0.2° Heading (RTK) 5 cm Real-time Heave, adjusted to the wave period up to 1 cm Position Key Features: Very Low Noise Gyroscopes 64-bit architecture for high end filtering processing Connection to external GPS and Odometer (DMI) IP 68 Enclosure 200 Hz Output Rate 2 years warranty Perfectly Suited to Marine Applications You can connect the Ellipse-E to an external dual antenna GPS receiver to get both accurate navigation and heading information without relying on magnetometers. Ellipse sensors are designed to operate in Marine and Subsea applications. Resistant to water and rugged to magnetic interferences, Ellipse-E provides an advanced heave which adjusts automatically to the wave frequency
