Abstract (en)
[origin: WO2021175502A1] The invention relates to a method and a system for determining the position of at least one object, in particular inside a building. In a method for determining the position of at least one object, at least four transmitters transmit circularly polarised signals and a receiver to be located receives the circularly polarised signals. At least two and in particular all transmitters transmit periodic signals of different frequencies, these frequencies being closely adjacent.
