Inerciální jednotka SBG Ellipse A Marine AHRS

The SBG Ellipse A Marine AHRS (Attitude and Heading Reference System) inertial measurement unit is a compact and robust sensor designed for marine applications. It integrates an inertial measurement unit (IMU) and magnetometers to provide reliable orientation data (roll, pitch, heading) and heave in dynamic environments, even in the presence of transient magnetic disturbances.

The Ellipse A Marine IMU provides high accuracy for its measurements:

Roll / Pitch: 0.1° (static)Heading (magnetic): 0.8° (under homogeneous magnetic field after calibration)Heave: 5 cm or 5% (whichever is greater), with automatic wave period adjustment (up to 20 seconds).

Yes, the housing version of the Ellipse A Marine IMU is designed to be robust and resistant to marine environments. It is IP68 certified, ensuring resistance to dust and water immersion (1 hour at 2 meters). Additionally, it meets MIL-STD 810G vibration standards (8 g RMS from 20 Hz to 2 kHz) and shock resistance (500 g for 0.1 ms), ensuring operational reliability even in extreme conditions.

The SBG Ellipse A Marine AHRS inertial measurement unit requires a DC power supply. The accepted input voltage range is 5 to 36 VDC. Its power consumption is very low, under 300 mW.

The Ellipse A Marine IMU is equipped with multiple communication interfaces for easy integration:

Serial interfaces: RS-232, RS-422, USB (up to 2 Mbps)CAN interface: CAN 2.0A/B (up to 1 Mbps)Synchronization inputs/outputs: 2 sync inputs (RS232), 1 sync output (TTL)Supports protocols such as sbgEcom (binary), REST API, NMEA, and other third-party protocols, with an output rate up to 1 kHz for IMU and Euler data.

The Ellipse A Marine IMU is compatible with several tools and platforms to facilitate its use and integration:

sbgCenter: Software provided by SBG Systems for configuration, monitoring, and data recording. ROS (Robot Operating System): A driver is available for full compatibility with this open-source software collection for robotics. Pixhawk: Open-source hardware platform used for autopilot systems in drones and other unmanned vehicles.

The Ellipse A Marine inertial measurement unit is designed to be very compact and lightweight. Its dimensions are 46 x 45 x 24 mm and it weighs just 45 g for the enclosure version. An OEM version is also available with dimensions of 29.5 x 25.5 x 11 mm and a weight of 8 g.

The SBG Ellipse A Marine AHRS inertial measurement unit (IMU) comes with a 2-year manufacturer's warranty.

No, each SBG Ellipse A Marine sensor undergoes a thorough calibration and factory test process across its entire operating temperature range. This ensures the product will meet its specifications throughout its lifespan without requiring recalibration.

Yes, the Ellipse A Marine IMU is available in two main versions:

A housing version, with IP68 protection, resistant to dust and water. Its dimensions are 46 x 45 x 24 mm and its weight is 45 g.
An OEM version, mounted on PCB, designed for compact integration. Its dimensions are 29.5 x 25.5 x 11 mm and its weight is 8 g.

The Ellipse A Marine IMU integrates high-performance accelerometers and a next-generation heave algorithm. It provides accurate heave data for marine applications, with an accuracy of 5 cm or 5% (whichever is greater). The system automatically adjusts wave period, supporting periods from 0 to 20 seconds.

The calculated Mean Time Between Failures (MTBF) for the SBG Ellipse A Marine AHRS unit is 218,000 hours.

The Ellipse A Marine IMU supports a variety of motion profiles to adapt to different applications. Profiles include:

Aerial: airplane, fixed-wing drone, helicopter, UAV.Marine: marine, submarine.Land: automotive, heavy machinery, off-road vehicle, pedestrian, rail, static, truck.

No, the technical documentation states that input protocols (Input protocols) are not applicable (N/A) for the Ellipse A Marine AHRS unit. It is primarily designed to provide orientation and heave data. It does, however, feature 5 Sync IN inputs for event markers or PPS up to 1 kHz.

The Ellipse A Marine IMU comes with comprehensive documentation. This includes installation guides, advanced configuration information and troubleshooting, as well as detailed manuals for smooth integration and operation. Test reports and firmware update procedures are also provided. These resources are designed to assist users at every stage.
