Application of the repeaters for indoor localization

This article shows the possibility of using GPS receiver for user localizations inside of the buildings in conditions where no satellite visibility is provided. There is inexpensive solution supported by signal of the GPS retransmission to provide localization data. Position description error for difference cases of decomposition aerial and difference number of signal repeaters were showed. To take under consideration the strong errors put by kind of system and the minimum of equipment requirement made the algorithm of transformation the data, were made. Introduced solution will allow for precise user localization at metro stations and underground parking area with minimum expenses volume and with popular GPS receivers and GALILEO ones in the future
