Overview
The Ellipse-N miniature INS/GPS from SBG Systems is a small, compact device that acts as an Inertial Navigation System (INS) using a GNSS receiver. The Ellipse-N has three gyroscopes, three accelerometers and three magnetometers. It produces high accuracy results and works on the MEMs-based Inertial Measurement Unit (IMU) principle.
The Ellipse-N runs on enhanced Extended Kalman Filter (EKF) which incorporates inertial data with GNSS, odometer and DGPS information for the precise orientation and the accurate navigation data even in the harsh environment.
This product is water resistant and is suitable for Marine, Land and Aerospace applications.
