UGV – Unmanned Ground Vehicles
An Inertial Navigation System (INS) provides real-time roll, pitch, and heading integrated with a GNSS receiver to maintain accuracy in case of signal outages (buildings, trees, tunnel, etc.).
The inertial sensor is also used to precisely synchronize and stabilize additional equipment such as LiDAR or Camera.

Tips
Magnetometer-based or GNSS-based heading (Yaw)?
Magnetic heading can be convenient for some application but requires a magnetic calibration as it is sensitive to iron-based equipment. Heading based on GNSS is not vulnerable to iron but requires an antenna to transmit L1/L2 signals from satellites.
One or two ntennas for GNSS-based heading?
One antenna is good enough for accurate heading in dynamic motion applications. A dual-antenna GNSS receiver will provide a more precise heading, especially when the vehicle is in slow motion, or often static. A dual-antenna solution also initializes more efficiently.
Which model for navigating in a harsh environment?
If your UGV is designed to drive in harsh conditions, you should consider RTK and multi-constellation GNSS models such as the Ellipse2-D. The choice of antennas will also be important, refer to your SBG rep for advice.
