Due to the unavoidable drift and biases of the inertial sensors (gyros and accelerometers), these systems have to be augmented by additional sensors in accordance with the dead reckoning. With the development of the laser gyro with which the highest accuracy can be achieved, and powerful computers also the development of the strap-down systems started which replaced more and more the former platform systems. Another milestone in the field of navigation was the development of GNSS, which is ideal for coupling with INS systems using the Kalman filter technique. With these hybrid navigation systems, a direct georeferencing of photogrammetric image and scanner data is possible. At the University of Applied Sciences Bochum different systems for aerial flights and for use in land vehicles have been developed in recent years. The latest developments in the field of micro-electro-mechanical systems (MEMS) have been affected in the past the development of inertial sensors and the augmentation sensors as well. Although these sensors do not reach the high accuracies of their predecessors, they are inexpensive and of light weight. The development of these sensors in conjunction with powerful microcontrollers led recently to the rapidly growing use of Unmanned Aerial Vehicles (UAVs) for photogrammetric applications. Especially the so-called Multicopter, which are able to rise vertically and hover over a point are an ideal platform for photogrammetric sensors. In this paper, the various sensors and inertial navigation systems and developments for navigation and control as well as for photogrammetric applications and direct georeferencing, which requires a special calibration method for determining the relative position and orientation of the various sensors, are presented.
