Ellipse-N: RTK INS with Single-Antenna GNSS

Name: Ellipse-N: RTK INS with Single-Antenna GNSS
Brand: SBG Systems
Availability: InStock

0.05° Roll/Pitch & 0.2 Heading

Ellipse-N 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. It combines an Inertial Measurement Unit (IMU) with an internal dual band, quad constellation GNSS receiver, using an advanced sensor fusion algorithm to provide accurate positioning and orientation, even in challenging environments.
