| Abstract: | This paper analyzes the error characteristics of Inertial Surveying System(ISS) and deduces the error state equation of ISS in motion.The analysis of the eigenvalues of the dynamical matrix of the system indicates that there are oscillations in three freguencies in system errors.The simplified error state equation and its analytic solutions are given,and the Position errors caused by gravity anomaly are discussed. |
