For precision carrier-based landing aid, the position of reference point on the top of island shall be precisely transferred to the landing point on the deck, so the position transfer error caused by the hull flexure is not negligible. As the existing method is not very applicable to measure the hull flexure, a new technique based on integrated Global Navigation Satellite Systems/Laser Gyro Inertial Navigation System (GNSS/LINS) is proposed in this paper. This integrated GNSS/LINS based measurement method is designed to monitor the hull flexure and set up an integrated GNSS/LINS measurement model based on raw pseudo-range and pseudo-range rate measurement and carrier phase differential positioning measurement to effectively eliminate the measurement error caused by cycle slip and multi-path effect from GNSS. It is shown by demonstration test and analysis that this technique has the capability to precisely measure the hull flexure, with the accuracy being better than 0.02 m.
