SS antenna offset Furthermore the data can be additionally corrected during a triangulation process described below To produce the initial position and attitude files for each image the data must be processed into a local rectangular reference frame This local reference frame Is defined to be Cartesian and centered in the project area and is used to support the attitude data and the triangulation The GNSS IMU processing Is an important step towards high quality imagery and accurate measurements derived from it The timing of IMU recording GNSS recording and sensor line recording must be done using a synchronized clock This allows the precise registration of each data recording event To perform data collection from imagery without triangulation care must be taken to handle each error source The data are then un compressed and organized into images usually in TIFF format metadata and positioning data These positioning data are essential to model the position and the attitude of the sensor during the flight and to thus recover the parallelism of the scanned lines The combination of positioning GNSS and inertial IMU measurements measured magnitudes and measured frequencies allows for generation of a precise and reliable trajectory position attitude with a resolution of 200 Hz depending on IMU ADS obtains the imagery up to a maximum frequency of 800 Hz 1 25 ms The first step in the post processing Is therefore the calc
