The advanced hyperspectral imager of GF-5 is a high spectral resolution camera, and it has outstanding recognition and classification ability for complex features and environments. The high accuracy geometric calibration is the key factor for the geometrical quality of satellite imagery. The geometric calibration model based on the pointing angle of the probe is used in this paper. The internal and external calibration parameters are solved step by step and some typical images are selected for experimental verification. The results indicated that the absolute positioning accuracy of AHSI can be stably better than 60 m (2 pixels) and the internal positioning accuracy is better than 0.5 pixels, the bands registration accuracy can be better than 0.3 pixels.
