System and method for estimating a location of a local device and a local device

摘要

The invention relates to a method for estimating a location of a local device. The following steps are performed:
A signal 11 is broadcast between at least one beacon 1 and the local device 2 at the location. A time of flight value of each of the signals is determined for obtaining an actual set of time of flight values. The location of the local device 2 is estimated based on the actual set of time of flight values and at least one reference set of time of flight values each reference set corresponding to a known location of the local device 2.
