The Ellipse 2-A is an inertial sensor with an integrated AHRS system, marketed by SBG Systems. It is precise, robust and reliable and comes in a miniature, lightweight format.
The Ellipse 2-A Inertial Sensor is part of the SBG Systems Ellipse 2 series. The tiny module is less than 5 cm long and includes:
High-performance, very low-noise 3-axis MEMS gyroscopes
3-axis accelerometers equipped with internal FIR anti-vibration filters
3-axis magnetometers and temperature sensors
An integrated AHRS for calculating pitch, roll, heading and heave
All connected to a processor for data calibration, coning and sculling
The serial CAN interface allows easy inclusion in automation applications using RS-232, RS-422 and CAN 2.0 protocols.
A variety of uses thanks to the Ellipse 2 Development Kit
