Research on the Method of Improving iGPS Dynamic Tracking Accuracy Based on Theoretical Trajectory Backward Compensation

As a result of the ongoing upgrading manufacturing industries, higher and requirements are being proposed for assembly precision. In particular, in industries that involve large-sized products, it is hoped accuracy can still be guaranteed as product size increases. The emergence indoor Global Positioning System (iGPS) will enable this demand to met. work, we have conducted in-depth research on measurement principles dynamic performance iGPS system. addition, based motion equation tracked target, an analytical method calculate compensation amount required measurements proposed. This suitable accurate actual trajectory target real time when theoretical known. We set up simulation environment MATLAB tested method. testing proved compensate effectively errors measurement.
