ZY-3 02, which was launched on May 30, 2016, is the second satellite in the ZiYuan3 series and mainly used for developing the civil space infrastructure in China. The laser altimeter, which is a core payload in ZY3-02, is the first laser altimeter experiment instrument of China for earth observation. The evaluation of the accuracy of this instrument is a crucial factor for stereoscopic mapping and occasionally even more difficult to improve than the planar. The basic conventional block adjustment was combined with the increasing accuracy of laser altimeter data and the characteristics of the laser altimeter data in the ZY3-02 satellite. The geometric imaging model of refinement general theory of satellite stereo images aided with the laser altimeter data was proposed in this study. First, high-precision tie-point matching in the conventional block and free network adjustments without constraints was utilized to obtain high-precision relative accuracy and absolute precision, which was not worse than that in original imaging geometric model. Second, the reference image point coordinates, which were used to map the target image point coordinates with the geometric model, could be acquired on the basis of the 3D coordinates of laser altimeter data and refined imaging geometric model of the reference data. Third, high-precision homonymous image points could be determined in the target images after the refinement process through the tie-point matching algorithm. Finally, the block adjustment with the homonymous point as the elevation control was performed to further process the imaging geometry model and compute the high-precision compensation parameters. The experiments in Hubei and Qinghai indicated that the elevation accuracy of the satellite geometry model refined using the laser altimeter data could reach 1.97 and 3.23 m. The comparative experiments in Hubei and Xinjiang areas presented that the system error became larger given the weakening of the control strength. The experiments discussed above demonstrated that the proposed method could effectively improve the accuracy of satellite stereo mapping. The application of laser altimeter data was subject to topographic relief. It could be more effective in the flat area but requires several necessary preprocesses in the mountain area before utilization. In practical applications, the laser data should be distributed evenly and no more than one track in the space interval.
