| Abstract: | Despite significant progress in GSP/INS-based direct georeferencing technology in the last decade,there is still room for improvement in terms of better accuracy. The main objective of this paper is the stochastic modeling of Inertial Measurement Unit (IMU) errors,which determines significantly the final performance of the GPS/INS integrated system. With the random constants,random walks and first-order Markov process models to characterize the stochastic errors of IMU,one Kalman Filter with 36 orders was m... |
