SBG Systems Ellipse-D: RTK INS with Dual-Antenna GNSS
0.05° Roll/Pitch & 0.2 Heading
Ellipse-D belongs to Ellipse series line of miniature, high-performance GNSS-aided inertial navigation systems, designed to deliver reliable orientation, position, and heave in a compact package. Combining an Inertial Measurement Unit (IMU) with an internal dual band, quad constellation GNSS receiver and using an advanced sensor fusion algorithm, Ellipse-D provides accurate positioning and orientation, even in challenging environments. It features dual-antenna heading for applications that require precise and stable heading in static conditions.

Frequently Asked Questions
What is the Ellipse-D: RTK INS with Dual-Antenna GNSS?
Ellipse-D belongs to Ellipse series line of miniature, high-performance GNSS-aided inertial navigation systems, designed to deliver reliable orientation, position, and heave in a compact package. Combining an Inertial Measurement Unit (IMU) with an internal dual band, quad constellation GNSS receiver and using an advanced sensor fusion algorithm, Ellipse-D provides accurate positioning and orientation, even in challenging environments.
Why use a GNSS-aided INS like the Ellipse-D: RTK INS with Dual-Antenna GNSS instead of GNSS alone?
A GNSS-aided INS fuses inertial measurements with satellite positioning, so the Ellipse-D: RTK INS with Dual-Antenna GNSS 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 Ellipse-D: RTK INS with Dual-Antenna GNSS available?
The Ellipse-D: RTK INS with Dual-Antenna GNSS is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
