Ellipse-N


 
General 
Product Name:Ellipse-N
Product Description:Ellipse-N is a small-sized high performance 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 runs an enhanced Extended Kalman Filter (EKF) which fuses inertial data with GNSS, Odometer, and DGPS information for excellent orientation and navigation data in the most challenging environments.
