Method for improving accuracy of trajectory correction using lateral pulse jets

The paper presents methods for trajectory correction using lateral pulse jets on flying devices using global navigation systems (GNSS). In the control algorithm, the activation time between two consecutive pulses, instead of being a given constant value, is determined according to the characteristics of the flying device and trajectory parameters. Results of simulation and comparison between cases show that the proposed method of trajectory correction is better than the remaining methods because it requires the smallest number of pulses within the threshold of impact point deviation.
