Trends in automotive inertial navigation
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.
