So far, there are too many examinations concerning the possibility of the application UAV in photogrammetric studies. Unmanned aerial vehicles are usually equipped with low cost and low grade Inertial Navigation System (INS). In relation to determination the value of the angle orientations of the camera on low cost UAV mainly inertial sensors based on micro-electromechanical systems are being used (MEMS). In this case, the typical accuracy of determining the angles of the platform can reach up

... o 0.5 degree. In the paper, results of comparison of the angle elements of exterior orientation between the transformation model from the INS sensor to camera sensor, and the aerial triangulation method are presented. Two research methods were used in this paper, i.e. the method of transformation between the frame of the INS sensor and the frame of the camera sensor and the method of digital aerial triangulation for determination of the angle. The research experiment was realized for 789 images data from Trimble UX-5 sensor. The flight mission was conducted above Liwiec river in 2015. The results of the comparison show that the mean difference of the angle elements of exterior orientation between both methods amounts to ±1.5⁰.
