Description
Ellipse2-E: External GNSS for Navigation.
Ellipse2-E is a versatile miniature inertial navigation sensor that connects to external GNSS receiver to provide navigation data, and to odometer for land applications.
It provides roll, pitch, magnetic heading, heave, and position.
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
- 0.1° Roll and Pitch
- Magnetic or GNSS Heading
- Position depends on External GNSS
- 5cm Real-time Heave
- Available in a light enclosure
- Full Development Kit available
Key Features
- Very Low Noise Gyroscopes – we have selected state-of-the-art MEMS sensors, especially very low-noise gyroscopes
- Efficient Vibrations Handling – high quality accelerometers with Internal FIR filters coupled with Coning & Sculling integrals to provide efficient vibration rejection
- Robust Position during GNSS Outages – for the INS modes (E, N, D), the internal Extended Kalman Filter fuses in real-time inertial and GPS data for enhanced position and orientation measurements in harsh environments (urban cancyons, tunnels, etc.)

Applications
UAV
Inertial Navigation Sensors for UAV Navigation and Payload Stabilization & Orientation. An Inertial Navigation System (INS) provides Roll, Pitch and Heading information which are fused with GNSS data for real-time, robust navigation — even in challenging conditions, near building or power lines for example.
UAV-Based Survey
Real-time and post-processing LiDAR stabilization and Point Cloud Georeferencing. An INS delivers motion and position information. It is used to synchronize and stabilize camera and LiDAR precisely while mounted onto the UAV. It is also used for accurate data geo-referencing in real-time or at the office using the post-processing software.
Gimbal Camera
IMU for Camera Stabilization, AHRS for Camera Orientation. Low latency between physical motion and output is critical in this type of application, additionally is high bandwidth and precise synchronization.
The Ellipse sensors show a total latency of less than 3 ms between motion and output. Furthermore, these units are carefully designed with signal conditioning and FIR filtering to provide very low latency and high bandwidth while protecting the measurement from vibrations.
Finally, we also pay attention to the gyroscopes and accelerometers synchronization to achieve the best accuracy.
