INDOOR POSITIONING USING PRESSURE SENSORS

摘要

The present disclose relates to position estimation in an indoor environment. In one example, a location server may receive a request for reference information from a wireless network device located in the indoor environment. The location server may determine a reference altitude and a reference pressure at the wireless network device. The location server may transmit the reference altitude and the reference pressure to the wireless network device for the wireless network device to determine its altitude in the indoor environment. The location server may also determine a reference horizontal position, and transmit the reference horizontal position to the wireless network device for the wireless network device to determine its horizontal position in the indoor environment.
