The ship deformation is an inevitable and severe problem for surface ships, especially when the ship is large or the sea condition is rough. Moreover, the positioning or detecting precision of the shipboard equipment will significantly decreases due to the ship deformation. So it is of great significance that estimating the ship deformation angle and restraining its effect in practice. Since ship...
Initial alignment is one of the key technologies in Strapdown inertial navigation system (SINS). It is divided into coarse alignment and fine alignment. The conventional method of fine alignment is to adopt Kalman filtering and uses single filter to estimate system states. In Kalman filtering, it is known that system model should be matched with actual system and the statistical characteristics of...
Since the MIMU/GPS has advantages of low-cost and small-size, it can be widely used in the field of vehicle navigation. For the traditional MIMU/GPS integrated navigation system, the Kalman filter is used to fuse the information of MIMU and GPS to achieve the goal of navigation and positioning of vehicle. GPS provides users with highly accurate three-dimensional position and velocity informations...
A Kalman-filter-based approach is presented for resolving 3-D surface displacements using multisensor, multitrack, and multitemporal interferometric synthetic aperture radar (SAR) measurements. Measurements from each interferogram are projected into the three reference directions and combined in the Kalman filter model with displacements determined from previous interferograms to produce updated displacement...
