Frequently Asked Questions
What is the OEM Ellipse-D: RTK INS with Dual-Antenna GNSS?
OEM Ellipse-D 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-D: RTK INS with Dual-Antenna GNSS instead of GNSS alone?
A GNSS-aided INS fuses inertial measurements with satellite positioning, so the OEM 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.
