Ellipse2-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.
High Accuracy for such a Small sensor:
0.1° Roll and Pitch over 360°
0.5° Heading (GNSS aided)
5 cm Real-time Heave, adjusted to the wave period
2 mGNSS Position
Very Low Noise Gyroscopes, High Quality Accelerometers
Ellipse2-N is a full-featured miniature inertial navigation sensor. It embeds the latest generation of GNSS receivers for a better satellite availability in harsh environments (i.e urban canyons). In addition to provide accurate position and velocity, the GPS aiding allows the Ellipse2-N to maintain accurate orientation even during long term accelerations. This advanced inertial sensor additionally accepts differential corrections for even more precise navigation data.
