Inertial Navigation Systems for Driverless Cars Testing and Integration
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 for a driverless car application.

Tips
Odometer data may be fused with our IMU and GNSS data in real-time to provide enhanced performance in harsh environments (urban canyons, mountain, forest, etc.).
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.
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.
