The invention belongs to the technical field of indoor positioning, and discloses a microsatellite base station positioning system and a method based on a single or multiple Bluetooth transmitting units. The positioning system comprises at least one microsatellite base station for broadcasting the identification code, coordinates, the flow and the room number of the base station, transmitter signal propagation parameters and working mode message information. A microsatellite base station positioning system on user equipment is used for receiving the signals of the microsatellite base station, analyzing the obtained message information and calculating self one-dimensional, two-dimensional or three-dimensional coordinates. Precision time synchronization and dedicated receiving equipment are not needed, user habits are not changed, and a general phone can be used to acquire the precision equivalent to that of outdoor positioning; seamless butt joint between indoor positioning and outdoor positioning can be realized; and the microsatellite base station is low in cost, low in power consumption, convenient to deploy and good in environmental adaptability and extendibility, and no external cable and no fiber is needed.
Description
technical field [0001] The invention belongs to the technical field of indoor positioning, and in particular relates to a micro-satellite base station positioning system and method based on a single or multiple bluetooth transmitting units. Background technique [0002] Indoor positioning technology is one of the emerging positioning technologies in recent years. Compared with outdoor positioning technology, indoor positioning usually achieves reliable positioning calculation in a closed and more complex space. At present, the main methods of indoor positioning include the nearest neighbor method, the geometric method, the scene analysis method, and the line reckoning method. Among them, the neighbor method and the scene analysis method are mainly suitable for indoor positioning occasions with low precision requirements. The positioning error of the line reckoning method accumulates over time, and it is difficult to be independently used as a high-precision indoor positioni...
