THE EFFECT OF DIFFERENT GNSS SOLUTIONS ON THE DIRECT SENSOR ORIENTATION ACCURACY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 Direct sensor orientation or direct georeferencing is the solution of exterior orientation parameters using GNSS\IMU data without ground control points. Accuracy of the system is based on GNSS\IMU integrated system accuracy.
