N2 - The Position and Orientation measurement System (POS) is an important part of airborne remote sensing system, it is mainly used to measure and compensate the motion errors of airborne sensors. As a kind of high accuracy measurement system, compensation of dynamic errors is an important part to improve the accuracy of POS. Inner lever-arm error which called size effect is a typical dynamic error, in this paper, theoretical analysis of size effect and how to deal with different kind of size effect error is presented, through simulation analysis and experimental study, the relationship between size effect and system vibration input characteristic is illustrated, finally, after the comparison of position navigation errors in different frequency and amplitude vibration input condition, the rationality of analysis in this paper is validated.
