Description

Ellipse2-A: Orientation + Heave by SBG Systems, is a cost-effective, high-performance Attitude and Heading Reference System (AHRS).

Factory calibrated from -40 to 85 degrees Celsius, this robust inertial motion sensor provides Roll, Pitch, Heading, and Heave data.

This light-weight sensor (45 grams) includes a MEMS-based Inertial Measurement Unit (IMU) integrating three gyroscopes, three magnetometers, and three accelerometers. Running an extended Kalman filter (EKF), the Ellipse-A provides accurate orientation data in both static and dynamic conditions.

High Accuracy for Such a Small Motion Sensor

  • 0.1° Roll and Pitch over 360°
  • 1° Heading (Internal Magnetometers)
  • 5 cm Real-time Heave, adjusted to the wave period

 

Key Features

  • Very Low Noise Gyroscopes
  • IP 68 Enclosure
  • 200 Hz Output Rate
  • RS-232, RS-422, and CAN Interfaces
  • Binary, NMEA, ASCII, and TSS Protocols
  • 2 years warranty
  • ITAR Free

 

Highly Rugged to Vibrations and Magnetic Disturbances

  • Vibrations: Internal FIR filters coupled with Coning & Sculling integrals to provide efficient vibration rejection.
  • Calibration: Intensively tested and calibrated from -40 to 85°C for consistent data in all conditions (the Calibration Report is shipped with the sensor).
  • Iron Disturbances: Ellipse sensors are highly rugged to magnetic disturbances. To go even further, a magnetic calibration tool is embedded in the inertial sensor. It allows quick in-field soft and hard magnetic disturbances compensation.

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.
