Ellipse-A: High-Performance AHRS Sensor

Name: Ellipse-A: High-Performance AHRS Sensor
Brand: SBG Systems

0.1° Roll/Pitch & 0.8 Magnetic Heading

Ellipse-A belongs to Ellipse series line of miniature, high-performance MEMS-based Inertial Systems providing a reliable orientation and heave in a compact package. It includes an Inertial Measurement Unit (IMU), a built-in magnetometer and runs an on-board latest generation sensor fusion algorithm. The IMU embeds high performance, industrial grade MEMS accelerometers and gyroscopes. Coupled with a cutting edge calibration across its entire operating temperature range and advanced filtering techniques, these accelerometers and gyroscopes will provide excellent performance, even in highly vibrating environment.
