Ellipse2-N: Single Antenna GNSS

Ellipse2-N: Single Antenna GNSS by SBG Systems is a small-sized high performance Inertial Navigation System (INS) with an integrated L1 GNSS receiver. It provides Roll, Pitch, Heading, Heave, and metric GNSS position.

Ellipse2-N embeds the latest generation of GNSS receivers for a better satellite availability in harsh environments (i.e. urban canyons).

Ellipse2 Data Sheet

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 m GNSS Position (GPS, GALLILEO, GLONASS, BEIDOU are supported)
• 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 models (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 canyons, 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.
