Check out this great article about accurate positioning for autonomous vehicles. Next-generation inertial measurements will figure the where-abouts of AVs with centimeter-level precision. by Reem Malik at ACEINNA.
Guidance and navigation systems tell autonomous vehicles where they are and where they need to go. These systems consist of GNSS/GPS receivers and an INS (inertial navigation system) which includes inertial motion sensors and inputs from odometry and steering sensors.
MEMS-based inertial sensors such as gyroscopes and accelerometers have long been used in vehicles as discrete components – for collision detection, airbag deployment, and electronic stability control. High-end IMUs (inertial measurement units) using MEMS or fiber-optic technology are commonly utilized in aircraft and tactical guidance systems and offer performance on the order of 10x to 1,000x higher than traditional MEMS sensors.
