摘要：Although some mature manufactures of airborne laser system (ALS) have been published for some years, however, in china, the development of ALS just is on the starting step. Shanghai Institute of Technical Physics (SITP), CAS is developing a new airborne laser instrument. It is the best difficult task to determining the systematic biases of ALS. The ultimate goal is to determine the master systematic errors and to correct the raw laser points. By analyzing the systematic error source firstly, the adjustment model presented in paper enable modelling and removing the actual errors in laser point sets. Interesting surfaces and regions can be determined by a least-squares plane fit through a subset of laser points. The proposal model of solution is based on integrating the observations and adequate control planes and the redundancy in the overlapping areas of laser data sets. It has been demonstrated that moderate slopes are sufficient to generate reliable solutions. In addition, the precision of ranging and scan angle aiming to the same target point is tested by laboratory experiment at the end of paper
