Group scheduling filtering algorithm for facilitating GPS positioning accuracy

In order to solve the problem that the current GPS (Global Positioning System)/INS (Inertial Navigation System) fusion system is easily to produce large time-varying error in the field of work safety science and technology,and meet the requirements for the accuracy of GPS positioning signals and the processing time of signal data,a group scheduling filtering algorithm was proposed,and it was compared with other algorithms through experimental simulation,including the fuzzy algorithm,machine learning algorithm and Kalman filter network algorithm. The results showed that the group scheduling filtering algorithm had great advantages in both positioning accuracy and real-time data processing,so it can be widely used in the aviation safety,ship safety,emergency monitoring,post-disaster rescue and other safety science and technology fields.
