Abstract
The invention relates to systems and methods for obtaining phase information and/or localization of tag devices. In particular, the invention relates to a system (100) for the localization of at least one tag device (10, 11), the system comprising: the at least one tag device (10, 11) configured to transmit a tag signal which is a frequency-hopping signal; at least one known position device (21 -26) configured to transmit a reference signal; and a localization device (31 -36, 40, 50) configured to localize the at least one tag device (10, 11) based on the phase difference of arrival, PDoA, of the tag signal and the reference signal. Further, the invention relates to a system (100) for the localization of at least one tag device (10, 11), the system comprising: the at least one tag device (10, 11) configured to transmit a tag signal; at least one known position device (21 -26) configured to transmit a reference signal; and a localization device (31 -36, 40, 50) configured to localize the at least one tag device (10, 11), the at least one tag device (10, 11) being subjected to be associated to one of the at least one known position device (21 -26) on the basis of distance determinations between the at least one tag device (10, 11) and each of the of known position devices (21-26).
