Abstract
In order to satisfy high-accuracy navigation, improve comprehensive calibration accuracy, improved two-point calibration based on Extended State Observer (ESO).Gave a brief analysis on traditional two-point calibration, restrictive navigating state and its shortage, then estimated platform horizontal errors based on EOS, improved the two-point calibration, then gave the algorithm simulation and numerical validate. The results indicate that traditional two-point calibration give a bad estimation result when carrier cannot satisfy navigating state, but new algorithm has the stronger applicability, reduce the restrictive navigating state and improve comprehensive calibration accuracy.
