Overview
The Ellipse-A from SBG Systems embeds a best in class magnetic calibration procedure for optimal heading and is suitable for low to medium dynamic applications. It calculates movement using a MEMS-based Inertial Measurement Unit (IMU) and provides accurate orientation information.
The Ellipse-A offers Advanced Filtering, sound calibration and allows you to set desired motion profiles accordingly. It combines three gyroscopes, three magnetometers and three accelerometers to provide information in both, static and dynamic conditions.
The Ellipse-A is suitable for Marine, Land and Aerospace applications. An OEM version is available for a more robust and simple integration module.
