Trajectory Simulation in Navigation System and Its Application

A sort of simulation algorithm of trajectory was presented, which can provide abundant data for the research of algorithm of strapdown INS. A trajectory was designed applying this algorithm. The improved rotation vector algorithm in the coning motion was tested based On angular rate of air body gained from simulation, which proved that trajectory simulation was important to the research of algorithm of strapdown INS. Based on positions gained from simulation and practical navigational control mode of some type of air, the trajectory was made and it was positioned and displayed in the electronic map, which proved the feasibility and validity of method.
