The increasing role of pushbroom cameras in large photogrammetric projects has fostered international interest in achieving a sound knowledge of this device. In addition, the classic software tools, implemented for frame cameras, need to be adapted to cope with modified aerial triangulation and self‐calibration procedures. This contribution presents the results obtained from the geometrical analysis and self‐calibration of the second‐generation pushbroom ADS 40 camera, the SH 52. For this purpose, a testfield was designed and built on the outskirts of Ávila, Spain and two blocks, flown at different heights, were imaged. A wide network of well‐defined control and check points was observed in order to provide a thorough assessment of the accuracy and reliability of the camera. Empirical analysis of a variety of models within aerial triangulation as well as the use of internal camera parameters has led to an evaluation of the camera's performance in a real‐life environment .
