Description
Ellipse-E is a small-sized high performance Inertial Navigation System. It provides Roll, Pitch (RTK), Heading, and Heave, and computes Navigation data when connected to an external GNSS receiver. It accepts Odometer aiding to maintain the best accuracy in challenging environments. This light-weight sensor (47 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.
