Driverless Car
An Inertial Navigation System (INS) provides real-time Roll, Pitch and Heading as well as a filtered GNSS Position that maintains a robust position in case of GNSS outages (buildings, trees, tunnels, etc.).
The inertial sensor is also used to precisely synchronize and stabilize additional equipment such as LiDAR or Camera.

Tips
Odometer Aiding
SBG inertial navigation systems accept odometer information and fuse it with inertial and GNSS data in real-time to provide even better performance in harsh environments (urban canyons, mountain, forest, etc.).
One or Two Antennas for Accurate Heading?
One antenna is good enough for accurate heading in most land applications. A 2 antennas GNSS receiver will provide a more precise heading, especially when the vehicle is in slow motion, and a lot faster initialization.
Using Post-processing for Further Analysis and Mapping
At the office, the Post-processing Kinematic (PPK) Software enhances inertial navigation systems performance by post processing inertial data with raw GNSS observables. This type of software is widely used to build precise maps of the environment. SBG Systems offers its own PPK software named Qinertia.
