  "textContent": "The passive combined indoor positioning system and method based on an intelligent terminal sensor, and is applied to the technical field of real-time positioning, can include a data collection module, a dead reckoning module, a geomagnetic matching determining module, a single-point matching module, a sequence matching module, a single-point positioning module, a sequence positioning module, and an error correction module. The system collects sensor data of a current location by using an intelligent terminal, and performs dead reckoning and geomagnetic matching based on the sensor data of the current location, so as to obtain a fusion positioning result of the current location through particle filter.",
