Ellipse 2 Micro INS (IMU)

Ellipse 2 Micro INS: satellite navigation

SBG Systems has designed 3 models for its Ellipse 2 Micro Series range offering various possibilities. The Ellipse 2 Micro INS has an embedded satellite positioning system connected to a GNSS receiver, which allows you to accurately determine pitch, roll, heading and position in addition to velocity and rotation.

This tiny system will give you all the accurate data you need to work on your next autonomous navigation application whatever the type of robotic vehicle, be it on the sea, on land or in the air.

Particularly robust despite its light weight and small size, the Ellipse 2 Micro INS will adapt to all on-board navigation systems.

Want to develop a satnav application?

SBG Systems has designed a complete development kit just for you, with:

• An evaluation board for working on INS applications using an ublox module
• Windows-based software for making the very most of your INS in terms of configuration, data analysis and C programming
• Unlimited technical support and INS firmware updates
