OEM Ellipse-E: INS with External GNSS for Navigation

Name: OEM Ellipse-E: INS with External GNSS for Navigation
Brand: SBG Systems

0.05° Roll/Pitch & 0.2 Heading

OEM Ellipse-E 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 external GNSS receiver, using an advanced sensor fusion algorithm to provide accurate positioning and orientation, even in challenging environments.
