Combined navigation loose composite structure design
Jan 16, 2019

The figure is a block diagram of the structure of the loose combination system. The difference from the tight combination system is that the measurement information used in the loose combination system is the position and velocity, and the difference between the position and velocity calculated by the GPS subsystem and the position and velocity calculated by the inertial solution is used as the Kalman filter input. The feedback correction and result correction of the loose combined Kalman filter are the same as the tight combination.
