Ellipse2-D Miniature Dual GNSS/INS

Ellipse2-D: Miniature Dual GNSS INS

Manufacturer: | Categories: ,

Ellipse2-D Miniature Dual GNSS INS from SBG Systems is a small sensor with high accuracy, providing Pitch, Roll, Heave, Heading and Navigation data. DGPS and odometer inputs can be used to enhance the navigation solution.



The Ellipse2-D uses an enhanced Extended Kalman Filter (EKF) and contains a MEMS-based Inertial Measurement Unit (IMU). These features allows the unit to combine GNSS and inertial data and suitable for use in diverse applications such as data geo-referencing, payload orientation and positioning, and motion and heave monitoring.

The unit offers a compact and cost-effective solution for accurate heading requirements. As it has a dual antenna heading, this eliminates typical magnetic calibration issues that allows it to be used in applications where the magnetic field is not reliable. The integrated Survey-grade L1/L2 GNSS receiver with two antennas allows unmatched position and heading accuracy.

This instrument is suitable for applications in marine, land and aerospace applications. It is ideally suited for wave measurement, motion monitoring, and onboard equipment (antennas, camera, etc.) stabilization and orientation, as well as entry-level mobile mapping and car motion monitoring.
