Self-driving vehicles require precise navigation information and global positioning systems like GPS and Global Navigation Satellite Systems (GNSS) Real-Time Kinematic (RTK). Unfortunately, these require an active communication system that includes things like GPS satellites to provide positioning information. This doesn't happen if enough satellites can't communicate with a receiver. In this case, inertial navigation systems (INS) that utilize an inertial measurement unit (IMU) need to be added to the mix. 

I spoke with ACEINNA's Vice President of Marketing and Product Development, Teoman Ustun, about what we might expect in the future. We wrapped up with a discussion about ACEINNA's new INS401. The INS module includes an RTK-enabled GNSS receiver, triple-redundant inertial sensors, along with the company's Positioning Engine. This low-cost system is designed for use in high-volume, L2+ and higher advanced driver-assistance system (ADAS) applications. It delivers centimeter-level accuracy and enhanced reliability during GNSS outages. The INS401 also provides dead reckoning using an IMU. It's qualified for automotive applications and certified to ISO 26262 ASIL-B level.
