SBG Systems OEM Ellipse-N: RTK INS with Single-Antenna GNSS
0.05° Roll/Pitch & 0.2 Heading
OEM Ellipse-N is part of a compact, high-performance GNSS-aided SMD inertial navigation systems, engineered for precise orientation, position, and heave measurements in a miniature form factor. This advanced solution integrates an Inertial Measurement Unit (IMU) with a dual-band, quad-constellation GNSS receiver, leveraging cutting-edge sensor fusion technology to deliver reliable performance, even in demanding environments. Equipped with dual-antenna heading, it ensures exceptional accuracy and stability for applications requiring precise heading, including in static conditions.

Frequently Asked Questions
What is the OEM Ellipse-N?
OEM Ellipse-N is part of a compact, high-performance GNSS-aided SMD inertial navigation systems, engineered for precise orientation, position, and heave measurements in a miniature form factor. This advanced solution integrates an Inertial Measurement Unit (IMU) with a dual-band, quad-constellation GNSS receiver, leveraging cutting-edge sensor fusion technology to deliver reliable performance, even in demanding environments.
Why use a GNSS-aided INS like the OEM Ellipse-N instead of GNSS alone?
A GNSS-aided INS fuses inertial measurements with satellite positioning, so the OEM Ellipse-N keeps delivering accurate position, roll, pitch and heading during GNSS outages — in tunnels, urban canyons or under jamming — where a standalone GNSS receiver would fail.
Where is the OEM Ellipse-N available?
The OEM Ellipse-N is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
How can I get the datasheet and technical documents for the OEM Ellipse-N?
