| Summary: | A switching strategy of positioning method combining GPS,inertial navigation with ultra-wide band(UWB)based on signal quantity and signal strength was proposed in this paper. An optimized positioning algorithm was provided based on loose combination of technology of psecudo-range measurement, Chan-Taylor collaborative algorithm and pedestrian dead reckoning according to the strategy above. The experiment result showed that the switching strategy was feasible and the positioning trajectory of the connection area was optimized,which provided a novel idea for indoor and outdoor seamless positioning technology. |
