The Working Group Navigation at the Institute of Geodesy has been highly successful for many years, both nationally and internationally, in the research areas of precise and robust positioning and navigation and can refer to a corresponding number of publications. In addition to the fields of satellite-based positioning (global navigation satellite systems), software-based receivers, interference analysis in the field of jamming and spoofing as well as signals of opportunity, the working group has many years of experience and expertise in the fields of integrated and inertial navigation. The working group deals with multisensor systems, i.e. the sensor fusion of GNSS (GPS, Galileo, GLONASS, Beidou), INS (inertial navigation system), cameras, LiDAR (light detection and ranging), radometry, etc., as well as optimal filtering (Kalman filter, particle filter and factor graph optimisation). The optimal combination of the sensors used in terms of accuracy, reliability, robustness and integrity, using a wide variety of filter algorithms, has in the past led to the development of navigation systems for a wide range of autonomous applications (e.g. autonomous driving, autonomous drones, autonomous compost turners, robots). The working group has a high-precision inertial measurement unit (IMU) that can be used as a sensor in multi-sensor environments and contributes to the verification of more cost-effective and smaller sensors (MEMS, etc.). There is also an indoor navigation laboratory with a camera-based tracking system which can be used to evaluate developed indoor navigation solutions.
