Tightly Coupled Integrated Navigation Algorithm for Hypersonic Boost-Glide Vehicles in the LCEF Frame
According to the trajectory characteristics of hypersonic boost-glide vehicles, a tightly coupled integrated navigation algorithm for hypersonic vehicles based on the launch-centered Earth-fixed redken shades 9gi (LCEF) frame is proposed.First, the strapdown inertial navigation mechanization algorithm and discrete update algorithm in the LCEF frame
