SBG Systems Ellipse Series INS
The Ellipse Series is SBG System’s most advanced miniature inertial range for motion, navigation, and heave sensing. This series includes the Ellipse-A for orientation and heave, Ellipse-E for external GNSS for navigation, Ellipse-N for single antenna FTK GNSS, and Ellipse-D for dual antenna RTK.
The Ellipse series features very low noise gyroscopes with state-of-the-art MEMS sensors. Their high quality accelerometers with internal FIR filters coupled with coning and sculling intervals provide efficient vibration rejection for enhanced precision. The INS models, the Ellipse-E, N, and D models, use an extended Kalman filter (EKF) to fuse inertial and RTK data in real time for reliable positioning in harsh environments.
Ellipse-A
Compact & Robust
Ellipse-A is an affordable and high-performance Attitude and Heading Reference System (AHRS). It embeds a best-in-class magnetic calibration procedure for optimal heading, and is suitable for low to medium dynamic applications.
Factory calibrated from -40 to 85°C, this robust inertial motion sensor provides Roll, Pitch, Heading, and Heave data.
Features
- 0.1° Roll and Pitch over 360°
- 0.8° Heading (Internal Magnetometers)
- 5 cm Real-time Heave
- Available in a Light Enclosure (OEM)
- Full Development Kit
- ROS Driver
Ellipse-E
External GNSS for Navigation
Ellipse-E is a versatile miniature Inertial Navigation Sensor that connects to external GNSS receiver to provide navigation data, and other sensors such as DVL or odometer.
It is best suited in case of specific GNSS integration or when wide interfacing capability is required. Ellipse-E provides roll, pitch, magnetic or GNSS heading, heave, and position.
Features
- 0.05° Roll & Pitch (RTK)
- Magnetic or GNSS Heading
- Position depends on External GNSS
- 5 cm Real-time Heave
- Available in a Light Enclosure (OEM)
- Up to 5x RS232/422 serial ports
- Full Development Kit
- ROS Driver
Ellipse-N
Single Antenna RTK GNSS
Ellipse-N is a compact and high-performance RTK Inertial Navigation System (INS) with an integrated Dual band, Quad Constellations GNSS receiver. It provides roll, pitch, heading, and heave, as well as a centimetric GNSS position.
Ellipse-N sensor is best suited for dynamic environments, and harsh GNSS conditions, but can also operate in lower dynamic applications with a magnetic heading.
Features
- 0.05° Roll and Pitch (RTK)
- 0.2° Heading (RTK high dynamics)
- 5 cm Real-time Heave
- 1 cm RTK GNSS Position
- Raw Data for Post-Processing
- Extremely small OEM module
- Full Development Kit
- ROS Driver
Ellipse-D
Dual Antenna RTK INS
Ellipse-D is the smallest Inertial Navigation System integrating a Dual-antenna, multi-band GNSS receiver, capable of delivering precise heading as well as centimeter level position accuracy in the most challenging GNSS conditions.
It provides attitude, heading, heave as well as navigation outputs.
- 0.05° Roll and Pitch (RTK)
- 0.2° Heading (Dual Antenna RTK GNSS)
- Immune to magnetic distortions
- 1 cm RTK GNSS Position
- Tiny OEM module available
- Post-processing with Qinertia PPK Software
- Full Development
- ROS Driver
