Automotive navigation represents a major backbone of the aspiring field of autonomous vehicles and autonomous driving. Being in knowledge of a vehicle’s position is crucial for many applications; however, the requirements for integrity, availability and accuracy are high due to safety-related aspects. Those requirements are met by means of sensor fusion, whereas internal as well as external sensors have to be taken into account. With an increase of the network capabilities of vehicles, automotive navigation is further augmented by interconnection of vehicles (Car2Car) and the communication with infrastructure such as traffic lights (Car2X). At the Institute of Geodesy, numerous projects were executed to determine accurately and reliably the dynamic state (position, velocity, accelerations, attitude, turn rates) in post-processing and real-time. Therefore, GNSS, INS, magnetometer, odometry and map data were used. Also, projects in the field of cooperative driving are/were executed. To evaluate the quality of the various positioning systems, the institute is in possession of a highly-priced inertial measurement unit called iMAR iNav RQH with ring laser gyroscopes and high-precision accelerometers. This is unique in the cientific field in Austria and Europe. Along with many other sensors and up to 5 GNSS antennas, this IMU may be attached to a tailored and calibrated roof mounting and can be used to evaluate the performance of any navigation sensor.
