SBG Systems Ekinox-D: Dual-Antenna RTK Inertial System
0.02° Roll/Pitch
Ekinox-D is an all-in-one Inertial Navigation System with integrated RTK GNSS receiver ideal for applications where space is critical. This advanced INS/GNSS comes with one or two antennas and provides orientation, heave, and centimeter-level position even during GNSS outages. An IMU is the core component of this inertial navigation system. Leveraging on MEMS technology and an innovative proprietary integration, the Ekinox-D IMU delivers an exceptional performance while maintaining a reasonable cost. In addition, a DVL or an odometer can be connected on Ekinox-D as velocity aiding inputs.

Frequently Asked Questions
What is the Ekinox-D: Dual-Antenna RTK Inertial System?
Ekinox-D is an all-in-one Inertial Navigation System with integrated RTK GNSS receiver ideal for applications where space is critical. This advanced INS/GNSS comes with one or two antennas and provides orientation, heave, and centimeter-level position even during GNSS outages.
Why use a GNSS-aided INS like the Ekinox-D: Dual-Antenna RTK Inertial System instead of GNSS alone?
A GNSS-aided INS fuses inertial measurements with satellite positioning, so the Ekinox-D: Dual-Antenna RTK Inertial System 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 Ekinox-D: Dual-Antenna RTK Inertial System available?
The Ekinox-D: Dual-Antenna RTK Inertial System is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
