Abstract (en)
[origin: WO2021183067A1] The disclosed invention refers to a system for indoor positioning comprising a multiplicity of antennas collecting satellite navigation signals emitted by a multiplicity of satellites, repeaters (each repeater with different set of satellites) for producing secondary signals different from said satellite navigation signals and propagating said secondary signals and at least one receiver capable of receiving and processing said secondary signals to compute location information. S aid secondary signals are contained in a lower frequency ISM band (such as 433 MHz) whereby free path loss is reduced and coverage is increased due to higher transmit power levels. Said at least one receiver is configured to execute a clock bias-based pseudorange triangulation algorithm.
